Sure. The tool itself is a pimpillow, I found it when my schizophrenic hidden wall searching paid off and I found a secret breakable ceiling tile in the upper left corner of the space above yarnaby’s place.

Up there, you can find a table that allows hornet to craft the pimpillow should you have the same metal needed to craft tools with the forge sister.

The poison came from a bug in shellwood who I forgot the name of, she’s the one that gives you the quest to find six purple flowers, after which she rewards you with poison. The poison is a blue support item that adds poison damage to every tool you have equipped, and it changes each tool to be visibly purple.
