Hi-5 is a peach-skinned hand emoji with a blue camo rubber band bandage around his index finger and blue eyes.
It shows mainly that it is not very bright. In the part of the movie where he tries to sneak away from the gorilla of the favorites section, a place where the popular emojis come together, he ends up going out the first time he tries this. He also put a candy corn (which he got from the Candy Crush game) again in his mouth a few seconds after he had already spat it out (even though Gene kept telling him not to). But he also has very good ideas, he is very clever and brave. Most times he is happy and friendly and a bit ambitious.
