So why associate Easter only with rabbits?
Disassociate those two things!
You could do an egg-painting thing for an Easter instead...
hold a paint-brush (or do the thing where you hold the paintbrush in your mouth), color-splattered shirt/apron/background, basket of unpainted eggs...
Or go for chickens, which LAY the eggs. Not baby chicks, but grown chickens.
You could also do an egg-hunt thing, with a hand-held magnifying glass (because searching for the eggs) and a background of tall grass/spring flowers with some eggs hiding in it.
You could do "Easter hats/dresses" (fancy and frilly and pastel colors) and a spring-basket.
You could do an Easter where it's almost all knuffel-room items instead of avatars (and then you could reuse some of your old art, make it easy on yourself!).
(I would like to say, those shirts that are like off-shoulder t-shirts with a support strap and with the bunny on them.... I'd LOVE to see that style of a bunny show up as a pet/animal item... especially if it were in the back left background, where it could be hiding from the avatar.
