Use this tool to arrange Wublin Island layouts for My Singing Monsters.

Features include:

Easily move Wublins around a grid to arrange your island.
Easily visualize polarity. (green is positive, red is negative)
Progress saves automatically and can also be imported/exported.

Controls:

Navigation: WASD/Arrow Keys or drag the screen
Click a Wublin's icon on the left to spawn it in.
Click and drag Wublins to move them around the grid.
Click on a wublin to mark it as "dormant". Its color will be set to grey and not be affected by other wublins, but will still affect their polarity.
Use export button to be able to copy your layout somewhere else
Paste a save into the same box and click import to override the current layout.

Pro-Tip: The Wublins are ordered in the list based on positive polarity. So Brump is first, it likes fleechwurm, which likes Pixolotl, which likes Scargo, etc. Poewk is at the end and it likes Brump. Monculus and Wubbox are not affected by polarity.
