Just put out your idea for a Super Smash Bros. stage. Here's mine:
Distant Spring.
A mostly flat stage, that takes place in the Distant Spring, from Pikmin. Half of the stage will be shallow water. In the background, there is a giant Smoky Progg egg, and if the match goes on for five minutes, the egg will hatch (in Pikmin, if you visit the Distant Spring on or before day 15, you can find the Smoky Progg's egg and make it hatch to fight it) and the Smoky Progg will come onto the stage as a boss. It can be damaged, similar to the Yellow Devil on the Dr Wily's castle stage, but when defeated, instead of creating an explosion, the Progg will leave behind a golden pearl that heals the person who takes it back to 0%. (Once the Smoky Progg is defeated in Pikmin, it leaves behind a Golden Pearl that gives you 100 additional Pikmin) If the stage is set to Final Destination mode, the Smoky Progg egg will still be in the background, but the Progg will not hatch out of it.
