While pretending to be mad scientists, Donny and Alma create a toy monster which all the other toys are afraid of until they get to know him and see that he's not so scary after all.
Tropes:
- Extra Eyes: One of the things that the other toys think should be changed about Charlie is that he has three eyes.
- Intelligible Unintelligible: Charlie can't talk like the rest of the toys, making grumbling noises instead. No one seems to have trouble understanding him though.
- Once Per Episode: Doc's Diagnosis: Torn MTL - Monster Tentacle Limb
- Pun-Based Title: A play on "eek!" and the game hide and seek.
