Tap-Tap the Golden

Tap-Tap the Golden is a gold Tap-Tap. He is found in Door Three of Baby Bowser's castle in the game Super Mario World 2: Yoshi's Island. The screen slowly moves through a lava filled cave as he jumps around you. You can hit him with eggs into the bottomless pits, but he'll just come back. Knocking him off the screen is the best option, and don't worry about running out of eggs, there's plenty of blue Fang bats flying around.

Golden Tap-Taps, called Super Big Tap-Taps, appear in Yoshi's Island DS, and they more than live up to their name. They are much larger than Tap-Tap the Golden and attack Yoshi in a manner similar to Chomp Sharks.

Trivia
He may be Tap-Tap the Red Nose ressurected, since the Nintendo Power Guide stated his introduction as "Tap-Tap the Golden is back", though they may have meant Tap-Tap the Red Nose since Tap-Tap the Golden had never appeared before.
