This picture triggered the same Calvin and Hobbes memory for me

Good to know that it wasn’t done personally, but we should avoid encouraging this behaviour without the full story behind it.

I hope the OP will come back to explain the circumstances of this picture (e.g food based colouring, dog knocked over dyes).

Willing to help out if you’re not able to find more helpers, but never done it before so will need to learn the tools.
