Mushroom Heights

Mushroom Heights, also known as Acorn Plains-4, is the fourth level of Acorn Plains in New Super Mario Bros. U. It is the first athletic course of the game, and introduces Groombats, and Ballon Baby Yoshi. This course is the first within the Acrobat Pack.

Features
The stage consists of vertically moving mushrooms, as well as ones that tilt in various directions. The enemies mostly conist of Piranha Plants of differing varieties. The Goombrats are introduced within this stage and act similar to red Koopa Troopas, who walk from edge to edge on different platforms, acting as an obstacle.

Star Coins
Star Coin 1: The first Star Coin can be spotted on a blue mushroom near the beginning of the stage. It rests on at the top of a ledge very high up. Use a Baby Balloon Yoshi or a Super Acorn to collect it.

Star Coin 2: The next Star Coin is also near a large blue mushroom platform, but is located directly underneath it. You'll near to use a Baby Balloon Yoshi or a Supe Acorn to collect it without falling to your death.

Star Coin 3: The last Star Coin is nestled between 2 giant Piranha Plants and a swaying mushroom platform. It can be difficult to collect the coin without getting damaged, so attacking and destroying the Piranha Plants are your best bet to nab it.
