Weirdland is a large Seboan Island and was part of My Madeup World. In My Madeup World it was a planet that was mostly owned by the Chukas and Plot-beans. There are the same animals at the Island, which has not appeared in any books although is mentioned. There is also an Island Videos Weirdland channel. Although it has a very minor role in The Islands, it was the main part of My Madeup World.
Weirdland was first mentioned by Splatter, when he suggests the Babies recruit Chukas and Amptos to fight the Shadows. Sammy declines this, as he says "Amptos are wild animals that would attack both sides in a war".
