Wally is a prankster who appeared in the past pictures from the episode "The Big Picture". He ruined one of Foster's house photos by activating a trap door under the stairs, where all the imaginary friends were standing.

A different kind of Wally (who was in fact a wall) appeared in "Duchess of Wails."


  • Wally can be seen as a parody of Waldo from the "Where's Waldo?" books, since Bloo tries to find Wally in the photos in "The Big Picture", and since both Wally and Waldo wear a red and white striped sweater.
  • He has a little to no lines at all.
