Rest Sublevel

Rest sublevel, also referred to as rest stop or rest level, is a general term used to describe sublevels in caves in Pikmin 2 that contain no or very few harmful enemies or other hazards, and large amounts of helpful items such as nectar, Ultra-bitter- or Ultra-spicy spray, or Candypop Buds. A somewhat common exception to the "harmless enemy only" rule is Doodlebugs, and Bulbmin are found in one case.

A fair proportion of rest levels contain geysers, and they are most commonly found in long and difficult caves, often before or after sublevels containing boss enemies. Such levels usually contain large amounts of flora, Unmarked Spectralids swarms, pipes which act as tunnels and water low enough for any pikmin to safely walk through.
