Wendell (Animal Crossing)

Wendell is a blue walrus from the Animal Crossing series. He is a traveling wallpaper/design artist. He gives you a free wallpaper/design if given fruit, turnips, or fish.

In Animal Crossing
Wendell will come randomly any day of the week at any time of day. You can find out if he will be coming to your town soon by asking Officer Copper if there are any going-ons. When he arrives at your town and you talk to him, he'll tell you he's hungery and asks for food. He will eat fish, fruit, or turnips. On weekends, he will give you a free wallpaper for giving him something to eat. On weekdays, he will sell a wallpaper to you. Some of his wallpapers you can't find anywhere else.

In Animal Crossing: Wild World and City Folk
Instead of giving out wallpapers, Wendell now gives you designs. He now appears from 6:00 am to midnight on a random weekday. He will give you a design if you give something to eat. If you give him fruit, excluding coconuts, he will give you a design you have already obtained. If given fish, he will give you a design only obtainable from him.
