There aren’t too many seasonal animals, but you’ll see them seasonally during their respective holidays.
I got Holly in December 10, 2008. She was a Build a Bear original character, and you’ll really only be seeing her around Christmas.
Hal is Holly’s brother. I got him on the same day, and I think he’ll only be around for Christmas too.
I got Daisy on March 8th, 2009, and yeah, she’ll only be here in the spring/Easter.
Eden is a wintery animal, but she will be appearing more than just in the winter. I got her on April sixth, 2015.
Those are all our seasonal animals! Check out the other groups!
