Shrimpo mostly comes off as unnecessarily aggressive and rude. Despite his cute appearance, he can be described as hurtful, selfish, and is also threatening, reaching the point of murder for an unknown reason shown in the interaction with Looey. Whenever he is not hating, he refers to himself in third person, boasting about how good he is.

Shrimpo shows barely any major depth throughout his personality, contrasting him from most stereotypical bully characters in most children's media who usually do have good hearts deep down or eventually get redeemed. He is an abrasive, short-tempered Toon who is relentlessly angry for no discernible reason. The most notable part of his personality is that he claims hatred for anyone, anything, and everything, and sees himself on a high level, occasionally praising himself and only himself, sometimes in the third person.

Shrimpo does not care about other Toons' feelings at all.
