Attack A: Pupet Gas - Dummymon expels a repulsive green gas that transforms its enemies into ventriloquist Dummies.
Attack B: Slapstick - Dummymon launches a punch or a slap on a spring to attack from a far distance. It can retract the spring afterward.
Dummymon is one of LadyMyotismon's loyal (and HIGHLY dangerous) servants, always believing he's actually made of flesh than wood, LadyMyotismon used this to her advantage by warping the poor Dummymon's mind. Rendering him servile to LadyMyotismon's commands.
(And yes, my intention was to make Dummymon look EXACTLY like Slappy from Goosebumps)
