Happy Tree Friends is a very popular yet highly graphic animated web series running form 1999-current day.
The 18th episode of the 1st season titled "You're Baking Me Crazy" air during 2000. The original version is presumably the same except for a different, the different version is that Flaky was the girl scout inside of Giggles. The reason for the change remains unknown but fans suggest it was because of Flaky (who was an unknown gender at the time) saw Lumpy without a towel.
This version of the episode is extremely if not impossible to find.
