Amos is mildly annoyed that he has to wait to give Mr. Giraffe a nose-bonk hello.
He already said 'hi' to Baab the sheep, so now all he can do is sit there awkwardly and try not to make eye contact with Baab, which would make things even more awkward. It's kind of like when humans keep running into the same person they just said 'hi' to repeatedly at the grocery store while they do the rest of their shopping...like seeing them in every aisle kind of awkward.
[sigh] Being a polite little bunny is hard sometimes!
