Mikey Gets Shellacne
"He...will be UNLEASHED!"
Donatello experiments with Mutagen as he tries to find a cure for April's mutated father, but Timothy, feeling lonely, drinks some of the Mutagen to form arms and legs and escapes into the city to look for April and make her his friend.
The episode starts off with Mikey showing his brothers a brand new show, SRMFF (which is similar to Space Heroes), which he found copies of in a dumpster. The others initially complain about how bad it's quality is, but then, after a few seconds, they are all addicted to it, like Mikey is with comics. Donnie leaves to his lab after watching a scene where a male geeky character is meanly turned down by a princess character that he likes. Donnie talks about April in front of the mutated Timothy, while trying to create an antidote from the Mutagen. However, he fails and, instead, the solution ends up getting frozen. He vows to create a cure in order to win April back but, as soon as Donnie leaves to think about this endeavor, Timothy's tongue ventures out of his containment tank and he uses it to take some Mutagen from a canister, before giving an evil glare.
Meanwhile, at Roosevelt High School, April vows to start fresh with her life and forget about everything that has happened to her recently. However, she is then knocked down by a hockey puck and comes face to face with Casey Jones, who tries to put April in the wrong by telling her that she shouldn't have blocked his puck. Right away, April doesn't like Casey because of his clumsiness, but he calmly asks her to be his tutor in Trigonometry, as he's been failing and could get kicked off of his hockey team. After April agrees to help him, they set up their first session in the park and April tells him not to be late. Later, on a rooftop that night, Mikey comes across a lone Pizza box with one slice left inside. At first, he's suspicous of it, but he then decides that he should have it. Unbeknownst to him, three figures are snopping around behind him and, before Mikey can make a move, he's tackled by his brothers. Mikey yells that he couldn't see them coming and Leo tells him that the keys to stealth are misdirection and camoflauge. Mikey is about to reply, but his brothers vanish again and Raph quickly surprises Mikey, who yells that stealth attacks are lame. While the others are busy doing their own thing, Donnie stakes out a park, knowing that April studies there for school by herself. However, he finds her and a boy teenager (Casey) there, swinging and talking. He suddenly becomes jealous and thinks that they are on a date, especially because Casey reaches out to wipe a smudge off of her face. Then, Donnie tries to get closer, but falls into a dumpster, startling the two. Back at the lair, he vents his jealousy of April "seeing" Casey, while also installing a voice box for Timothy. Timothy tells him that he also likes April, but Donnie is too upset about what he saw to pay any attention to him. At that moment, Splinter calls him into The Dojo, which allows Timothy to start drinking Mutagen from another canister that Donnie left out. Splinter tells Donnie that he will teach him to like falling down, which confuses Donnie. After Splinter knocks him to the floor a few times, Splinter tells him that the point of the exercise is that no one can be forced to like something. Of course, Donnie realizes that he means that he can't force April to like him. Unbeknownst to either of them, Timothy has formed sludgy arms and legs because of the Mutagen he drank and he breaks free to look for April on the surface. He tries to get some one to help him find her, but everyone is clearly terrified of him.
The Turtles head out in search of Timothy, while Donnie tells his brothers about everything that has happened, including that the fact that he has been following April and found out that she's been 'dating' with some one. The Turtles stop and split up into two teams, with one (Leo and Donnie) going to the park and the other (Mikey and Raph) going to April's apartment. However, they both miss her, as she is walking home with Casey. At that moment, Timothy finds April, but Casey moves in front of her, trying to fight off the monster with a lead pipe. He manages to hold his ground for a few seconds before he gets knocked out of the battle and April takes over the fight. Timothy tries to talk to her, but she continues to attack him as Casey jumps back in, only to be kicked out again. Timothy tries to grab April once he has hit her down. Just then, Casey rides up on his bike, saves April, and speeds out of the alley with Timothy close behind. Casey manages to throw what's left of the lead pipe at Timothy, which knocks him into a truck. Casey and April then escape. Timothy tries to pursue them, but Mikey and Raph find him and fight him. Mikey gives the young mutant a new name, which is "Mutagen Man". Before 'Mutagen Man' can kill Raph, Leo steps in and frees him by cutting of one of the beast's hands.
Donnie stops Leo before he can do any more damage and explains that Timothy wants to help them. However, the mutated Timothy tells them that he wants April to be his friend and does not want to help Donnie out. Just then, the giant mutant 'powers down' because he hasn't consumed enough Mutagen, so the Turtles succeed in getting him into The Shellraiser. On the way back to the Lair, Raph asks Donnie why they're bringing 'Mutagen Man' back. In addition to saying that 'Mutagen Man' wanted a friend because of how he spoke about April, Donnie says that the mutant Timothy's DNA could help him create an antidote to cure him and April's dad. During the conversation, however, he drinks two more canisters of Mutagen and busts out of the Shellraiser, looking for April. The Turtles prepare to split up again, but Donnie tells them that he knows where Timothy is going: April's apartment. At the apartment, Casey is carefully scanning the area for any more mutants. Before April goes inside, Casey talks about when their next "date" should be. At that moment, 'Mutagen Man' prepares to capture April, but the Turtles show up and Leo tells them to keep the mutant in the alley so that Casey won't see any of them. April notices the fight and keeps Casey away from the scene by telling him to bike in the other direction, which works. She looks into the alley and thinks that the Turtles were responsible for 'Mutagen Man' attacking her. The Turtles barely fend off 'Mutagen Man', but Donnie comes up with a plan to use stealth to distract him. Donnie goes into The Shellraiser and comes out with a canister full of Mutagen that's hinted with a freezing solution. Timothy, desperate to have this, quickly chugs it down and suddenly freezes. The others root for the victory, but Donnie sadly looks at the motionless mutant and renews his vow of curing him.
Back at the Lair, the Turtles are watching SRMFF, while Donnie sits away from the TV, mourning the fact that both April and Timothy are out of his life. Splinter shows up and asks Donnie how he feels. Donnie's response is negative, as Timothy was his responsibility and the fact that he went after April probably means that she won't want to see them again. Splinter supports Donnie's words, but says that there is hope that she'll come back to them without being forced to. Donnie then looks up to the SRMFF episode and sees the princess character kissing the nerdy kid, restoring his optimism...
- "You can not make someone like something."
- This marks the first appearance of Casey Jones.
- April returns in this episode.
- This is the first episode that Mutagen Man was on the surface.
- April's Tessen reappears.
- This is the 6th episode that focuses on Donnie.
- We see Roosevelt High School in action for the first time, but makes its second appearance in the series.
- This is the first time Space Heroes is mentioned but not seen.
- We also see "Second Time Around" when Casey is walking April to her apartment.
- It may be possible that when the Turtles were trying to get Mutagen Man away from Casey, while he and April were having a conversation about their next "date", April was trying to get Casey to not look at Mutagen Man, which may mean that she is helping the Turtles (even though she doesn't realize and doesn't care about that).
- In the opening scene, The Turtles watch a show called SRMMF V, a parody/reference of 1980s anime such as Voltron: Defender of the Universe (aka Go-Lion) and the bad dubbing of anime from that era.
- The mecha of the five heroes loosely resembles Voltes V from the anime of the same name, and the team's speech patterns resembles that of the Power Rangers. Their ridiculously long team name is a reference to Super Robot Monkey Team Hyper Force Go!, a show, executive producer Ciro Nieli previously worked on.
