Animal Kingdom · 动物王国
Sunflower's paracosm.
It's a world full of talking animals living inside kingdoms. The two main kingdoms are Cat Kingdom and Dog Kingdom.
Meta
Sunflower can enter her paracosm, normally by flushing herself down a toilet, but any method works actually, as long as you know about it and intend to enter. She just likes the absurdity.
Real time passes when you are inside, though not always linearly, so it's best to keep a watch on you. It tells you what time it is outside.
