I don't see how an animal crosser could even possibly fight. What would it do?
You can come up with special moves for anyone if you try hard enough
Neutral B - Slingshot (from Wild World). Tap repeatedly to shoot rapid-fire weaker, slower, short-range shots or hold to gain more range, damage, and knockback. If you hold B you can use up/down on the control stick to change the angle. The projectiles
are affected by gravity
Side B - Axe. A slow but high-damage/high-knockback attack in the vein of Kirby's Hammer
Up B - Fishing Rod. Doesn't actually cause the Animal Crosser to move upward but it serves as tether recovery. If it comes in contact with an opponent while the Crosser is standing on ground, he'll flick the rod and pull his opponent in (from which you can throw him/her), kind of like a cross between Link/Samus's grab move and Bowser's Koopa Klaw in Melee
Down B - Shovel. The Animal Crosser digs a hole in the floor, and any opponent who steps in it is trapped for a few seconds. Works like the new Pitfall item except the holes go away on their own after a short while, and opponents aren't trapped for as long
Final Smash: <Bees> A beehive drops on the middle of the stage and a horrified expression appears on the Crosser's face (just like what happens when you knock down a beehive in Animal Crossing). A swarm of bees appear and follow the Crosser for a while, attacking any opponents they come across (no knockback but temporary stun and lots of damage). The Crosser himself doesn't actually get stung (if the bees catch up to him, he just stands there waving his arms to fight them off, but he's still controllable. Maybe in the end they catch him and his face is swollen for the rest of the match?). After a few seconds, the bees leave and the Final Smash ends.
