Where is Portia's house key on Animal Crossing City folk?

Answer 1

Every animal loses their key sometime in Animal Crossing City Folk. In this case, it's Tabby. Talk to her a couple of times, and she'll say something about the river. Fish in the river, not the ocean, and fish for fish like you normally would, and one should be a key.

Answer 2

when somebody says they lost their key, talk to them until they mention the river. then fish ( it will be a very small shadow) and eventually you will catch the key and the character will give you a gift for returning it.

Answer 3

When a neighbor's key s lost in your town in Animal Crossing, it can be in various places... The most common place to look is in the river. The key will look like a fish but will be a lot smaller. There is no definite place to where a key is to be found
