New Super Mario Bros. U Blind Walkthrough Part 52: Restricted Access

Most stages here have some sort of gimmick that prevents you from doing something which makes them quite a challenge! They're quite fun to play through despite that difficulty.

-Time Stamps-
0:00 Larry's Groundless Battle
6:12 No Climbing Allowed
17:23 The Trial of Bullet Bill Hill
23:11 Spin Jump, Get Dizzy (Possible reference to "Touch Fuzzy Get Dizzy"?)

Enjoy!
