Where To Find Bunny Day Recipes?

[DinoTown]

Hi!
I'd like to know where everyone has been finding their Bunny Day recipes. So far, I've been given 1 by Zipper, 1 from a villager who pinged me and the others that I have all from popping balloons, but I'm sure there's other ways to get them.

How have you been finding your Bunny Day recipes? How many recipes are there to find in total?

There are some that wash up as a message in a bottle.

I actually found one on the shore just before I saw this post, haha! Thanks!

I'm finding lots of them in Balloons
