Although not he isn't as smart as Donnie, Casey Jones has proven himself to be a good inventor creating many weapons to help in his vigilante war on the streets. In the one hour specail of Wormquake! we see another of these great weapons, explosive pucks! These pucks pack a powerful punch to take out anything that stands in their way, and have proven quite useful in taking out the Kraang, plus put a stop to the Newtralizer's plan to destroy New York in Newtralized! Casey Jones truly has an inventive mind.
With one whack of his hockey stick, the explosive pucks go flying through the air, looking harmless, but there are tiny explosives attached underneath. When the fuse runs down, you better get out of the way and fast! You definitely don't want these pucks to score a goal.
