It's a Shoe-In

'''Kutsu o Haite GO! GO!' ( クツをはいてGO！GO！ With Boots On, GO! GO!, unofficially known as Castle à Go-Go) is the sixteenth Japan-only e-Reader level of Super Mario Advance 4: Super Mario Bros. 3''. It takes place in a castle-like area, with many spikes in the level, requiring the Goomba's Shoe for navigation. This level contains many Thwomps, Koopa Troopas and three Advance Coins. At the start of the level, Mario will land on a floating P Switch instantly, making navigation to the first Goomba's Shoe possible and providing access to the first Advance Coin. This level indicates that it is possible to defeat Thwomps with the Goomba's Shoe.

Trivia

 * A fan-remade version of "Kutsu o Haite GO! GO!", created in Super Mario Maker was featured as one of Nintendo's weekly course selections. Subscribers to the Nintendo Newsletter received a mail on October 24, 2015, which included these course selections, and the highlighted level of this article was remade into one of them by a user called Nigge from Australia, as E-16: Castle à Go-Go!. The level is obviously designed in the vain of the NES Super Mario Bros. 3, and its ID is BC9E-0000-0082-FFF5.
