Makes the game more fun and it will give you an edge against your opponents.
As electrodes are about to explode, you can pick them up and throw them. This is only right as they turn black, and it requires good timing.
In Corneria, you can blow up the guns on the front of the ship. This is best done using your down a attack on them, but you will probably die once they're gone.
You can actually hurt people with Luigi's show off
Once you beat everything in the game, including all the events and unlocking everything, you can catch Celebi in a Pokeball. this will get you the celebi trophy.
Peach can rarely pick up other things besides turnips when she uses her down B. For example, bombs and I've heard beam swords and stuff.
Samus, Link and young Link's grab moves can be used to grab ledges from a distance.
There's an event 51 after you beet everything else. Use Jiggly Puff's down B. That's how I beet it.
If you go to training mode and open Pokeballs, the Pokemon in the last one you opened will appear first if you go to 1 player.
When you get a Superscope if you shoot 5 of those little bursts of 3, shoot 3 full charges, and get hit when you're flashing yellow doing the 3rd one, the scope will get infinite ammo.
There are award/trophies for beating 1 player modes with every character.
