Or how about one of the following for Poochy (or a mixture of 'em)?
1) Appears, but does nothing but look around, pant, and wag his tail for several seconds. Then he leaves.
2) Appears, moves over to an item (Poke Ball and related) and bats at it with his paw playfully (like how he bats Yoshi eggs in SMW 2). After three bats of an item Poochy ends leaving the stage.
If somebody grabs and throws the item though before the third bat, Poochy will go and fetch it knocking over anyone in the way for damage and knockback in order to bring the item back to the item thrower. Poochy then leaves the stage.
3) Appears, moves over to an item, and then picks it up with his mouth. He'll run away from everyone trying to get them to run after him risking falling off the stage in the process. If somebody knocks the item out of the mouth before Poochy falls out, Poochy will then leave the stage.
