Ouroboros' favorite.

Exploration Stage: Dream Studio
From: Conductor
Description: I searched all over the studio but could not find Ouroboros. Martha tells me he is stubborn. Maybe he doesn't want to go home yet and is hiding. Let's try to lure him out with his favorite toy, a stuffed fish. Will you look for him with me?
Completed: Yes, that's it. Ouroboros loves stuffed fish. As soon as he saw this, he crawled out... but then he noticed the carry bag, realized our intentions, and hid again. He's a smart guy, totally.
