The game is already pretty hard without challenges. Oh boy. Hmm....

Tank Buster: Defeat any Zombitorium Manor level without using ZombiFreeze on Gargantuar Zombies.

Too Cool For School: Beat any U of Z level using only Bamboo Shoots to kill zombies.

SCIENCE!: Beat Sweaty Palms-Level 23 without using Snow Peas or any plants obtained after Frostbite Falls.

I only made these up on the spot actually. But I think at least one of them should be possible.
