The Warp Zone is over the first block on the left. You can jump on the left side of this block to grab the corner and re-jump. This also gives the possibility to get to the right side of the level without going through the disappearing corridor.
The bandage is in the pit on the right, you can get it using a double-jumping character (like Ogmo).
Trivia[]
- 10 Horns is the only level in the entire game to have both a Bandage and a Warp Zone in the same level.
