Tiny Floating Whale

The Tiny Floating Whale first appeared in "Rose's Room". Steven wished for it to appear in his mom's room. When the whale spoke, it was Rose's voice.

Appearance
The whale is tiny, it floats, and is pink. It occasionally squeals and spews water from its blowhole.

Trivia

 * 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 voice was indeed Rose's voice, because Susan Egan (voice of Rose) confirmed it through a tweet to a fan.
