Initially, the aliens came across as threatening, careless, destructive, evil invaders.
However, it is later revealed that they are actually docile, gentle creatures who only arrived to look for Kirby, as well as they have visited Oakey Oaks to collect acorns. They only attacked the town because they thought the townspeople were trying to hurt Kirby.
