What is the secret ending of ty the tamanian tiger 3

It is the special ending that plays after the credits (You can only view it if you have completed the game 100%).
PS2/XBOX/GAMECUBE: At the end of the game, right after the credits, you are treated to a cutscene showing Fluffy's decapitated tail with Professor Karlos coming in and taking it with him.
GBA: At the end of the game, you are treated to a screenshot of Fluffy's decapitated tail with the words To Be Continued...on the bottom of the screen; possibly hinting a future game.
