Slip Slidin' Away (Super Mario Advance 4: Super Mario Bros. 3)

Slip Slidin' Away is the seventeenth level of World-e in Super Mario Advance 4: Super Mario Bros. 3. This card was released in Series 2 in Japan. Its official difficulty rating is ★★★★☆. It was released only in Japan initially, but it later became available internationally with the Wii U Virtual Console release of the game in 2016. The level has five Advance Coins. The key art featured Larry Koopa. It also features the only 3-Up Moon in the game without the player using a blue switch card.

Layout
The level is made almost entirely of Ice Blocks, and primarily features Bumpties and short jumps, as well as Donut Lifts and Stretch Blocks in some areas. The beginning of one area also features a couple of White Blocks. One point in the level is an auto-scrolling area in which the screen begins to move back and forth, moving faster each time and revealing more of the area until a Warp Pipe becomes visible, at which point the screen stops scrolling.

Advance Coins

 * 1) On the Ice Block platform to the left of the Amazing Flyin' Hammer Brother is a red Koopa Troopa, and later is a Warp Pipe. The Ace Coin is in the pipe, underneath two Frozen Coins. The player must use Fire Mario's fireballs and the Koopa Troopa to get it.
 * 2) The Ace Coin is on a set of Donut Lifts only accessible by using a flight power-up.
 * 3) In the second area of the level, the third Ace Coin is located on the second set of Stretch Blocks in the area with the Donut Lifts between them.
 * 4) If the player stands on the center of a set of three Donut Lifts, they drop down to an Ice Block below; continuing down, the Ace Coin is hovering over the pit at the very bottom.
 * 5) In the third area of the level, the Ace Coin is on the very left side of the room.
