Out of the gatchapon you get a wand! It looks like it would be the sort of thing a magic girl would have, but instead of a heart or a gem on the end, it's a crab.

When you wave the wand, a crab appears! If you wave it again, another crab appears! Keep waving, keep summoning crabs. Big ones, small ones, ones with adorable hats on. Twirl the wand and the crabs will disappear again. But the best part is: all of these crabs obey the will of the summoner.
