This would be a variation on "following," but more cooperative. Glitchen "holding hands" would share in the rewards of actions like harvesting, mining, restoring. They would be visually linked and move as a unit, but each glitch could perform a different action: i.e., one glitch mines the sparkly while the other milks the butterfly above it.
Of course glitchen could hold hands just to demonstrate affection and it would be nice if it could provide a low-level periodic mood boost.
Unlike following, this would only work with two glitchen at a time. Kumbaya, baby!
