Super Mario Maker - BiSiPi

[NICKtendo DS]

I finally got a 30th Anniversary Mario amiibo!
With that, I updated and cleaned up World 1-1 (New). The Big Mushroom actually appears in that course, even in NSMBU style. It appears in place of the Mega Mushroom. However, in styles other than Super Mario Bros., the Big Mushroom does nothing. Well, except giving you 1000 points. It's the thought that counts!
The ID is updated in the OP.

EDIT:
Added World 6-5 from Super Mario Bros. 3. It's the underground level where the Super Leaf or Tanooki Suit were mandatory, as you needed to fly up the right opening.

Here's a DLC idea I just had:
Boss Door: Takes you to a sub area different from the one the Warp Pipes take you. Defeating all enemies in this area counts as clearing the stage. Can be used as the main goal by making the standard goal unreachable, or as an alternative goal.
