I really love the little drawing you added! I like the idea, maybe the patissier offers to pay the animals in homemade pet treats since it'd be unfair to make them to it to free (in my opinion!). Maybe some of the animals can have prominent personalities? Like the rabbit is the leader/is in charge and is not tempted to eat the cake but the dog is, but the rabbit keeps trying to remind the dog to wait because the patissier will reward them afterwards? Maybe there's a cat who just can't be bothered to help?
I like the idea of different animals having very different roles in the team, I was thinking of maybe having a parrot so that I could have some aerial shots of the dog being carried across the town to the wedding venue? With shots cutting back to the street with the rabbit sprinting across the town to meet the parrot and dog at the venue?
