Fliqpy's scream from "Remains To Be Seen" reused in many Happy Tree Friends episodes.
PS it's hard to hear Fliqpy's scream in Double Whammy Part 2, but it's still there :)
The sound is used from "Remains To Be Seen Happy Tree Friends" and from many other Happy Tree Friends episodes and is made by "MondoMedia". This video will be used on htf wiki. This content is not made by me
