Lantern and Drinking Bird are both voiced by KirbyRider1337.
Planetbucket22 currently voices Jack, Journal, Circle and Thing and had previously voiced Candle, Quince, Toothbrush, Vanilla and Walky Talky.
Promoted Fanboy: KirbyRider1337 who was the winner of Planetbucket22's previous show, Object Crossovers, recommended two of his characters (Lantern and Yogurt Cup) to partake as contestants on the show as his prize. Additionally, he also voices Lantern and later Drinking Bird.
Throw It In!: In "What Camp: Part 1" Planetbucket22 as Jack accidentally read Cotton Candy's line instead of his actual line which would explain why Quince and Sundae, two well-off contestants, were there in the show. Planetbucket22 decided to keep the mistake to add to Jack's character of being defective while the actual line is later used for "Keep An Eye", 5 episodes later.
