The player runs a Snail Park similar to the one from "Gary in Love." They start with an empty food bowl which must be filled with snail food to attract snails. Better quality snail food attracts rarer snails but must be bought with coins. The player also has a variety of tools they can use. They are watering can which the player can use on snails to give them energy, a camera to take pictures of new snails to put in their photobook, a brush to brush the snails and a ball of yarn to make them play. Snails can also request the player to use the watering can, brush or ball of yarn on them. If these wants are fulfilled, the player earns coins. Coins are used to unlock items, which are decorations for the park and buy better snail foods. Coins can also be found hidden throughout the park in sparkling places. The goal is to unlock all items and all snails and earn all achievements.
There are a total of 54 unique snails, all with different names and favorite things, which can be items (or hints at the item involved) or food types, which can be found in the photobook. Some of them are taken from the show or references to real people. These are the snails, the brackets indicate the favorite thing:
