It's the Froggy Chair from Animal Crossing.

How does one obtain Froggy Chair?

You can either find a Froggy Chair in a village chest, or craft one by surrounding a Bell with Lily pads.

Known Bugs:

- Occasoinally, you may get stuck when trying to sit in a Froggy Chair. This can be fixed by relogging.

- Sitting doesn't always sync properly in multiplayer.

This is the first mod I've made and unfortunately I don't know how to fix those bugs.
