Make Believe Day, or simply Make Believe for short, is a Rilonian festival that takes place in the Autumn season. It was featured in and created specifically for an episode of the television show based on the toy of the same name, The Adventures of Teddy Ruxpin, titled Autumn Adventure. It's almost like a primitive version of one of the ancient Celtic festivals that eventually led to the creation of the night we know as Halloween, Samhain. The festivities of this day include wearing costumes, be they scary or not, dancing around a fire in celebration, and parading around in said costumes.
