The army builder set includes 6 Mousers with interchangeable battle-damaged parts to customize them, plus the debut appearance of Shredder’s Spybot, and as a bonus, extra scene building accessories like VHS tape, pizza slice, rats, and cheese wedge. The Mousers are an all-new sculpt based on the cartoon and feature multiple points of articulation. They can even be combined with the weapons from your Turtle figures! The rats are also compatible with the Rat King figure, so you can load him up with more of his loyal subjects.
