Rolling Hills

Rolling Hills is the first world of Mario vs. Donkey Kong: Tipping Stars. It is a grassy plain, with a backdrop similar to that of the New Super Mario Bros. series, and introduces the first mechanic in the game, Girders. The only Minis which appear in this world are Mini Marios and Mini Peaches. Mini Marios debut in Level 1-1, while Mini Peaches start appearing in Level 1-4. There are two bonus stages that are set in this world, B-1 and B-2. For enemies, only one Mini Shy Guy and two Circus Kongs appear across the whole world, and one Cursed Mini Mario in Level 1-8.

Trivia

 * This world is very similar to Coaster Hills in Mario vs. Donkey Kong: Mini-Land Mayhem!, as both worlds have the same music (from Super Mario Bros. 2), both end with Hills, both are grassy plains, and both introduce two new minis (Mini Mario and one other mini introduced in the first Multi-Door level of their respective games).
