Carl the Collector Episode 2 The Fake Mustache Collection/The Lint Dinosaur Collection >Carl and his friends meet up in the park to create lint dinosaurs for Lint Dino Monday. During the meetup, Nico creates a lint monster, diverging from the planned theme of the day. When Carl voices his opposition, Nico leaves to set up her own Lint Monster Monday meetup. As Carl continually opposes creating lint monsters, Arugula and Forrest join Nico while Lotta and Sheldon stay with Carl. Carl and Nico antagonize each other as they create their lint creations, before they start throwing acorns at each other's creations. When this culminates in Carl throwing mud at the lint monsters, which Nico blocks, the friends decide to resolve the conflict by working together to create rules for playing together. Under these rules, the friends ultimately decide to create lint dinosaurs, with time set aside for making lint monsters.
