She is very tall and very shy. He has spikes and is a bit of a grouch. In Savannah School there are many types of animals and every morning all the students say: "Good morning in the morning!", as they enter. Well, not everyone. Giraffe Julia has a very long tongue and makes a mess with her words. Everyone laughs at her as she gets tongue-tied during the morning salute. Everyone except Paco, who always defends her and tries to cheer her up. But what are those words she says each morning: "watermelon day" and "banana day"?
