The Jack-in-the-box Shadow (voiced by Takahiro Mizushima) is a Jack-in-the-box/pigeon-themed Shadow Monster that appears in the Episode 20 of Ressha Sentai ToQger.
The Jack-in-the-box Shadow is a Shadow Creep in service to Miss Gritta armed with the Cuckoo Clock Door from which he can fire an energy beam and the Juggling Clubs as hand-held weapons. He is sent out by her to gather darkness on behalf of General Schwartz. He delights in using his wacky illusions to make people laugh, as, anyone who laughs in his presence will then be sprung into the air, thereby creating "a hell of laughter." Anyone in his presence who laughs is subject to this, even other Shadow Line members, like Miss Gritta, and himself.
Jack-in-the-box Shadow would then be brought back as a ghost, or rather, a copy by Tombstone Shadow, alongside Fence Shadow and Pin Spot Shadow to back him up in his giant battle against the ToQgers. He was destroyed again by Diesel-Oh's Diesel Missiles.
