You can just see the conversation in Glendale:
Disney Suit: "We gotta do something with this Imagine Pavillion thingy. It's not making any money! Sure, a half million a year off the purple dragon, but there's no-one going in there!"
Lead Imagineer: "Well, the fans love Dreamfinder and Figment, we gotta bring them back."
Disney Suit: "Who?"
Lead Imagineer: "Dreamfinder was the original host back when the park opened."
Disney Suit: "We can't go backwards! No one's gonna care about a character from 30 years ago!"
Lead Imagineer: "Mickey Mouse, Snow White, Peter Pan"
Disney Suit: "Oh yeah, they're 30 years old too! So, is will this dreamfinder sell merchandise?"
Lead Imagineer: "He's very popular."
Disney Suit: "I can't see him on a T-shirt."
Lead Imagineer: "Look, let us bring him out at
D23 and show you how popular he is."
Disney Suit: "What's D23?"
Lead Imagineer: "The convention in August!"
Disney Suit: "Oh that thing. Fine, fine...sure, sure."
