Mario Clash is probably best known as "the one game Mario fans never remember". It's a surprisingly solid 3D remake of Mario Bros. that probably would have been successful had it been released on literally any console other than the Virtual Boy.
Mario getting squashed, likely by either a second player (which is impossible since a Virtual Boy link cable was never produced), or an enemy.
Mario falling (slipping?) and landing on his backside. A similar animation can be found in the original game.
Mario's face appears squished in-game, while in the tile version it appears normal.
