Let's Challenge New Super Mario Bros. U (1-Castle Lemmy's Pendulum Fortress): Spin Jumps Only

Let's Challenge New Super Mario Bros. U [German/HD/100%/Challenge] (1-Castle Lemmy's Pendulum Fortress): Spin Jumps Only New Super Mario Bros. U will be a special project again! For each level, I'll present you with a specific challenge that you can play yourself. You can read the general rules for the challenges below. Level played in this video with the corresponding challenge: Oak Grove Castle (Lemmy's Pendulum Fortress): Start without power-ups; do not collect power-ups; you can only walk and spin jump, so you cannot jump or run normally. You must let Lemmy attack for at least 30 seconds before you can attack yourself (difficulty 4/10). For the Let's Play:    • Let's Play New Super Mario Bros. U (Part 3...   General Rules: -You must start each level with certain power-ups and may only collect certain power-ups in that level. Yoshis also count as power-ups. If you have to "start without power-ups" in a challenge, you begin the level as little Mario. -You may never use checkpoints. But there are exceptions, which I always explicitly mention. -You may never be hit. So even if you have a power-up and take damage, you must restart immediately, even though you haven't died yet. There is an exception here, too: you can be hit with Yoshis, since Mario doesn't take damage in this case. -The challenges are only considered completed when you touch the flagpole at the end of the level or defeat the boss. You may never use a secret exit, only the normal exit. -Challenges in towers and castles generally only apply up to the boss door. From then on, you must let Boom Boom attack for at least 15 seconds when fighting him, and in a fight against one of the Koopalings, you must let the Koopalings attack for at least 30 seconds before you can attack him yourself. Special rules apply to all other boss fights, which will be explained in more detail at the relevant point. -Each Let's Play part consists of exactly three levels, and each level also has a challenge. The Let's Play videos are released every other day at 4:00 PM, and the corresponding challenges for the three levels played are released the following day at 3:30 PM, 4:00 PM, and 4:30 PM. So you have one day to complete the challenges before you see my (failed) solution to the challenge. -Each challenge is given a difficulty level from 1 (very doable) to 10 (extremely difficult). -Have fun! :)
