Tall, Tall Mountain

Tall Tall Mountain is a level in Super Mario 64 & Super Mario 64 DS that. It features a high mountain with all kinds of obstacles on the way to the top. The hat stealing monkey Ukkiki is featured here as well as the blowing cloud named Fwoosh. The dangerous aspect of the level is that almost the entire path around the mountain is thin and near a cliff face. Like it's painting, Tall Tall Mountain is surrounded by giant mushrooms, one of which has a Power Star. The top of the mountain has a flat surface and railing, and is next to a waterfall that leads to the start of the level.

The fans favorite secret slide entrance is a wall on a cliff and can be accessed by jumping into it (you'll notice the cliff face ripple when Mario gets too close).
