|Family||Muffy Crosswire (imaginer)|
|Cartoon debut||"The Friend Who Wasn't There"|
|Voiced by||Jonathan Wilson|
He is seen once again in "Muffy Misses Out," this time appearing much more like a physical stuffed animal; it is unclear whether Muffy is imagining a stuffed animal or Waldo is an actual stuffed animal. She is seen blow drying his fur when she feels lonely and mad about her friends not following her advice. She seems to be talking to him to console her feelings.
