Map of the Butterfly Passage

Features

The main section of Butterfly Passage is a rather linear network of platforms and ladders leading upwards that you'll enter from a red, bloody butterfly. An optional path can be found by going to the right after climbing a few ladders that leads to a platform where there is sometimes a plant-like NPC that reacts to a variety of effects.

At first, the path will be surrounded by butterflies, plants, and whisks, but those elements get slowly replaced by whipped cream covered by ladybugs. This finally leads to a monstrous slime creature being prodded at by a fork and spoon and crawled all over by ladybugs whose mouth serves as a door leading to Whipped Cream World.

A small, isolated section of this area can be entered from Whipped Cream World, containing a giant ladybug with a hole through its back. Surrounding it are smaller ladybugs, butterflies, flowers, and rectangular street lamps. The butterflies may turn toward Urotsuki when walking by. Entering the back of this ladybug leads to the Overgrown Condominium.

Trivia

Before version 0.111c patch 1, this world connected to the Butterfly Forest.
You were previously able to destroy a construction sign blocking a grayish monster's mouth using the Chainsaw effect, leading to a house with a strange white fish with weird flower-like protrusions on its back which teleported the player to the Blue Forest. Nowadays, the monster is unreachable.
