Rocky

"'A spirit found in the mountains. One of its pleasures is to roll boulders downhill.'"Flint, also known as Rocky, are Stone element seirei that can be recruited by paying them a certain number of Blue Gummy Frogs. They only appear if you have caught a lot of Gummy Worms. Flint can be selected as the starter Hero/Heroine element for a medium difficulty. Chocolat Cracks also uses the stone seirei. Its special power raises defense power.

They appear as bopping grey rocks in-game.
