Andrew gets festive during the inaugural Halloween edition (00:03:47) of TMNT Shellcast #042: Mutagen Monster from season 3 episode 24 of the Teenage Mutant Ninja Turtles 1987 tv series.

In the tv episode, Shredder plans to hijack trains carrying chemicals for mutagen production, but Bebop and Rocksteady's mistake causes a collision, creating impure mutagen. The mutagen transforms two bulls into a colossal mutant, leading to chaos. The Turtles and Shredder independently attempt to control the mutant, but in the end, the Turtles use an atom smasher to stabilize and revert the mutant back to two ordinary bulls, while Shredder faces another setback in his plans.

In this honorary Jackie Robinson (00:09:45) podcast episode, Andrew, Jon, and Chris participate in Show & Tell: Halloween Costumes (00:04:49), before Chris eats very cherry pie pizza (00:10:07).

Three Power-Up: Respins (01:56:49, 01:59:12, and 02:01:53) and one Power-Up: Combo Slice (02:01:17) ultimately results in hot dog and stuffed crust pizza (02:01:57).
