Early in the game, you'll have the opportunity to choose one of three animal companions: Ricky the Kangaroo, Dimitri the Dodongo, or Moosh the Flying Bear. Your choice will affect certain areas of the overworld, as each companion provides unique traversal and combat abilities. While you only choose one for your main playthrough, you can experience the others in a linked game.

- Ricky: Can jump over 3-tile gaps and punch enemies. He's excellent for navigating areas with many small pits.
- Dimitri: Can swim up waterfalls and eat almost anything. Ideal for water-heavy regions.
- Moosh: Can float over 3-tile gaps by hovering. Useful for areas with large chasms.
The companion you choose will determine which specific paths are open to you in certain parts of the overworld. While the main dungeons are always accessible, some optional areas and Heart Pieces might require a specific companion's ability. Consider your preferred playstyle and the challenges ahead when making your choice.
