This won't be a ship. They can work together ok but not completely.
Status: not a super bad pair but a very messy first fusion
Puppeteer won't be in a ship not yet. Insanity is not mental to even be in one not now or in the future. Unless we have an insane person like her then yes.
Appearance: Four hands two float two normal. One normal leg and foot then a foot that floats due to Puppeteer's body.

Headshot. Slightly derpy. Which is adorable in my opinion.
