At first I was just sort of laughing because it was similar to the fish, and it just turned to exorcising a 2spooky4me. "GET OUT OF THERE" *voice squeak*
The fish only slurs its words when the head is bent out. The neck of the fish automatically snaps back towards the default position of laying flat against the wood, so it requires electricity to move its head outward. It has just enough power to sing, but when it tries to move the head and sing at the same time, it taxes the dwindling batteries so much that the singing becomes distorted.
Someone explained this last time it was posted. I figured it was my turn.
Perhaps it didn't.
But I'll wager that the explanation is more necessary than the relatively constant themed *********** from various accounts.
So I don't feel too bad even if it was totally redundant.
