This is a rare sound effect that is not on the Warner Bros. Sound Effects Library from Sound Ideas. It's basically Warner Bros. Animation's equivalent to Sound Ideas, TIP TOE, CARTOON - XYLOPHONE TIP TOE, LONG from the Hanna-Barbera Sound Effects Library. This should not be confused with Hollywoodedge, Funny Metal Clink CRT041402 from the Cartoon Trax Volume 1 library.
