Very cute and inspires some familiars of your own, but none of them are really usable in the sense of the "Find Familiar" spell. If you have a DM who's willing to let you have a pet a lot of these can be really fun to try.
Clever descriptions. Not at all what I thought I was getting. 3 stars for the humor. 0 for the actual usability. 5 for layout and design.
