The Cheese Phone is a phone designed for Master Splinter, and it looks extremely similar to cheese. This could very well have been created by Donatello. It is to be used for true emergencies only. It first appeared in Wormquake!. The Cheese Phone makes its second appearance in Return to New York. The Cheese Phone makes it's third appearance in The Fourfold Trap.
- The Cheese Phone is a joke reference to the Bat-Phone from the 1966 Batman TV series, as both phones are gimmick themed, on a table under a glass case and are used for emergencies only.
