Stage: The Impact Site

I personally thought that the "Distant Planet" was a really stupid concept for a Pikmin stage. Why couldn't they have named it after one of the stages? I think that the Impact Site could be a very similar stage to the distant planet, with a few exceptions. One thing that could change would be that there would be something instead of a bulborb at the right. Maybe a wall that could be broken with enough damage or another piece of scenery. The ship in the background would still remain there.

Item: Teddy Bear

The teddy bear was an item in Earthbound you could buy. It would follow you around and take certain damage for you from enemies for around 200 health points. I think it would be an awesome addition as an item, because it's a unique concept.

Assist Trophy: Ivan

 

Ivan should be the final of the three assist trophies to appear in Smash Bros. 4. He could use his Earth PSI or his staff to attack enemies.

Trophy and Sticker: Balloon Fight Enemy

The only enemy in Balloon Fight that you can defeat. It is important enough in my opinion to be both a trophy and a sticker.

Sticker: Marcus McCloud

The son of the greatest mammal in all of Corneria, Marcus has never been seen in action, but should get a little bit of recognition. I'd say a sticker would do the trick.
