The Yummy Coconut Drink was one of the items in the beach store. This Yummy Coconut Drink, when purchased, would automatically be consumed and you would be given more energy to do actions. Since energy for actions is no longer needed these items have become obsolete. If purchased the items do not go to your inventory they are directly consumed, but the consumption does nothing because actions no longer require energy.
This item cost 8 YoCoins.
