This is Jet's favorite toy. incandescens gave it to Jet when he was a tiny guy, and he's latched onto it and calls it his "baby monkey" and he puts it to bed every night, and carries it with him to places he's not that sure of.
It's interesting because Jet's been given dozens of stuffed animals, but this is the one he latched onto.
And, for the trip, he's put his monkey into a safe place with all his trains. So I guess he's coming with us to San Diego.
