The Tiny Floating Whale, as its name suggests, is a tiny floating whale. Its body is circular with a small tail at its back. It is medium pink with a lighter pink belly. It has a big smile with white teeth. Its eyes are small, dark and ovular-shaped. It occasionally squeals and spews water from its blowhole.
Steven wished for it to appear in his mom's room. When the whale spoke, it was in Rose's voice, unbeknownst to Steven.
In his mom's room, Steven wished for the whale to give him "some fin" for a high-five.
- Having spoken, the Tiny Floating Whale shows that creations of Rose's Room can react to different situations and stimuli, but the extent of one's imaginative control over these creations is unknown.
- The Tiny Floating Whale is made of clouds, like most things created in Rose's room. This can be seen when Steven grabs onto the whale when falling.
- The Tiny Floating Whale closely resembles the Golden Whale from the games Castle Crashers and BattleBlock Theater, made by The Behemoth. This is likely a coincidence.
