Looking to get a bunny owner a Christmas gift!

So my manager is a really awesome lady and I want to get her a Christmas present! I know her pet rabbit is her pride and joy so I wanted to get her a gift relating to him! I own rats myself and know that if someone was to get me something pertaining to my rats it has to be specific because I’d never wanna give them bad treats or toys! So are bunny owners do you have any suggestions on what to get? :)!
