The Easter Costume is a retired costume that was first released in April 2009 in Account Upgrades and re-released in March 2016 and April 2019. Easter pets are pink, dressed up in an Easter Bunny costume, with a traditional Easter basket and purple butterflies surrounding them. Some of them even carry carrots! Since the Lati and Sindi are based on rabbits themselves, they are white with blue eyes. If you can impress the Easter Bunny on the Forums [during Easter] she might give you this costume.
