Boing! units may move through friendly units during their move. If a Boing! unit would end its movement inside a friendly unit without also being in contact with an enemy unit, backtrack along its path until it is in a legal position (at least 1’’ away from any units). Boing! units do not count as "contacting" terrain (e.g. for the purposes for Dangerous Terrain tests) unless they begin or end their move on it, but bouncy units are still blocked by impassable terrain.
