You cannot.
There isn't an action reply code to see a UFO on animal crossing because you can without it, (on animal crossing Wild World and City Folk). On a random day, a UFO will float above your town. You shoot it down with a slingshot, and that is how you get a UFO in your town. There are no AR codes needed.
I wouldn't use action reply an any games. it destroys your system and the game. and breaks the warranty. there are some cheat codes that don't hurt your game and you don't have to use the action reply. But some codes dont affect your game and or System and they work really well.
Trees lots and lots of trees
You need an 'Action Replay' game cartridge, they are found in many stores and online. They come with a pre-installed amount of codes, including some for animal crossing. But the cartridge also comes with a CD in which you can use to download more codes in mere seconds!I hope i have been a help to you!:)
Yes, you can insert the action reply code wire to back of action reply card.
