Spot

 Spot  is a pig that lives inside of Oscar 's  trash can  on Sesame Street.

He appeared in Sesame Street episode 2073, where he was played by a live pig.

Spot later became an unseen character for several years. Although not featured on screen, in episode 3782 Spot, (as well as Oscar 's elephant Fluffy ), was said to be missing fellow pet  Slimey  (who had gone to the moon); & he was heard using a jackhammer to help get Curly Bear to take her nap in episode 4078.

Spot finally re-appeared on camera over 20 years later (this time as a Muppet), appearing in episode 4178 where he received a mud bath from Mike Rowe.
