Friends are nice to have, but for a platform game hero, they can be hard to keep. With all the difficult running, jumping, and sliding you have to do, what if your sidekick can't keep up? He could fall down a pit, get stuck behind a door, be left behind by a moving platform, or dozens of other inconveniences that get in the way of keeping an adventuring party together. But there's a solution to those problems. This trope is distinct from but may overlap with Exposition Fairy, Fairy Companion, Spirit Advisor, and Mission Control. Not to be confused with Party in My Pocket or Took a Shortcut.
