Spine Coaster Connections, is the first level of Superstar Road in New Super Luigi U. It is unlocked when all of the Star Coins in Acorn Plains are collected. The Final Battle in Peach's Castle must also be completed to unlock Spine Coaster Connections.
The level begins on a platform with a ? Block, leading up to a Bonecoaster. The Bonecoaster travels down a section of track with a row of coins, followed by a Mega Fuzzy and groups of Fuzzies. More Bonecoasters follow, along with another Mega Fuzzy. A section of three Bonecoasters then follows, with Mega Fuzzies blocking the path throughout the area. The section leads to a single Bonecoaster, which takes the player to the Goal Pole.
- Star Coin 1: Before jumping off the second Bonecoaster, the Star Coin appears right above a Fuzzy.
- Star Coin 2: In the set of three Bonecoasters, the Star Coin appears above the middle one.
- Star Coin 3: Shortly after the second Star Coin, this Star Coin will appear above the bottom Bonecoaster.
- Shortly after the first Fuzzy, an 8-bit Luigi will appear in the grassy land above.
