Job 31:
The Star Fox stage I'm submitting is Out of this Dimension from the SNES game. Players fight on the slot machine, which occasionally dispenses giant, hazardous coins. Sometimes, an Arwing will appear and shoot players. Like on Corneria, it can be used as a makeshift platform.
As for Metroid, I'll submit Planet Zebes from the first game. Same as it is in Smash 64, but without the Ridley cameo.
Job 32:
I agree with the choices for Yoshi's new Side and Up Specials. However, I'll be submitting a replacement for the Ground Pound, which is his stomp attack from Super Mario World. When used, Yoshi hops a short distance off the ground and slams his feet down upon landing, creating a small shockwave.
For Wario, I'll be submitting brand new moves. His Neutral Special is called Bomb, which is a reference to the ones in Wario's Woods and Wario Blast. Wario will throw the bomb and it'll explode after a short time. It can be moved by hitting it or grabbing and throwing it. His Side Special is Flaming Wario, where he engulfs himself in flames and runs around, dealing damage to whoever he touches. Puffy Wario is his Up Special and has him inflate and float upwards before deflating and falling back down. Lastly, Wario's Down Special is Snowman Wario. A snowball encases his body, allowing him to attack opponents via rolling at them.
