Lemon is a character who was supposed to be in Battle for Grandma Again, before the show got cancelled.Lemon is a ripe yellow lemon.It's unknown what her exact personality is like, since shes never made any major appearances. Though from their poses in the intro, we could assume that she might be a cheery happy-go-lucky type character.Lemon was the only BFGA character who was armless.
Their suggested personality might be a joke on how Lemons are sour but she isn't.
