Legoshi

Honestly, when Legoshi gets jealous all he would have to do is walk up to you and the animal you were talking to would always run away in fear.  Not just because he's a Grey Wolf, but also because of how tall he is.

Louis

Louis tends to get possessive and doesn't like you hanging out or even talking to other animals. When he gets jealous, he would always make a big scene and be dramatic about it.

Hal

She doesn't get jealous often, but when she does she waits until you are alone so she can tell you how she feels.

Juno

Juno gets jealous of everything. She is very clingy towards you and is always by your side. When she does get jealous, she would walk up to you and try to get your attention.
