1x17 - Mush-Mush & the Mushables

When Lilit creates a 'friends tree' mapping out who everyone is best friends with in Mushton, she realizes Muddler has no friends at all. Unable to accept this, Lilit slips away to try and befriend him. But Muddler's perception of friendship is somewhat unique, meaning Lilit now needs the help of her two best friends, Mush-Mush and Chep, to escape from Muddler's clutches.
