a brownie bunny birthday

Daisy's birthday is on August 7th.  She tells me she wants a brownies and bunnies swimming party.   I'm brainstorming ideas for it.  She told me her current favorite color is pink.  Her second favorite color is purple.  I don't really like pink and purple together, so I said, "what other colors do you like?".  She said turquoise and green.  Then she said her favorite color was orange.  Maybe we could do all the colors with dark brown.  That would be cute.  I saw these crepe paper medallions here, and thought it would be fun to do something with them.

I searched "brownie birthday" on Google, and found these:

And I found instructions here to make this bunny pinata:

What do you all think?  Do you have any ideas for us?
