The Little Bird and the Caterpillar (2017)

"The little bird has plenty of peace and quiet high up in its tree, at least until an unexpected guest shows up. The brash caterpillar's keen on devouring the green leaves that the little bird has cared for so tenderly. During the ensuing showdown, the two fail to notice that someone else is hard on their heels, and this character's craving a more savoury snack."

Unfortunately the movie The Little Bird and the Caterpillar is not yet available on HBO Max.
