Hopper is a black and white crested penguin with a yellow beak, red eyes, and long, straw-like eyebrows (like the Rockhopper Penguin) which give him a somewhat angry or grumpy expression. He initially wears a Dragon Shirt. His eyebrows are similar to Mathilda's.
Below is a brief description of the cranky personality. For more information, click here.
Cranky villagers will usually appear in a grouchy or agitated mood and are more difficult to befriend than other villager types. When talking to the player, cranky villagers tend to become angry if the player disagrees with them or refuses to do a favor. Like all cranky villagers, Hopper will be invested in his hobby and will often challenge the player to various competitions. He will easily get along with jock, snooty and other cranky villagers, and occasionally lazy and normal villagers as well. However, he will find it hard to socialize with peppy villagers, as they will seem overstimulated or immature. Hopper will also enjoy spreading rumors of other villagers.
In Animal Crossing, Hopper's house starts with Cabin Series furniture in it. He also starts with four totem poles and some more random items like barrels. Hopper starts with three gyroids: A Tall Droploid, Tall Gongoid, and Mega Timpanoid. When he has a stereo, he will play Lucky K.K. on it.
Animals constantly ask Hopper how he got his name, and he tends to make up long, absurd stories about wild things he did as a baby. The fact of the matter is, his parents just wanted to name him "Hopper".
In the movie, he was not a main character. Instead, he was the film's comic relief (appearing in the foreground/background throughout a film, not knowing a character's background information). He is seen fishing all year round in the same spot, near the bridge by the river. Throughout the film, he catches a variety of things, excluding fish, but at the end credits finally catches a small fish.
