Zombie Wario got a fork in his knee because the Cook from WL2 and 3 put it there (for not appearing in WL4?)
The pictures in Wario's room in the first stage of WL2 are not of Wario but a relative of Wario.
Wario has coins with his face on them because he's the dictator of Wario Land.
Wario can't be Fat Wario in Smash because of balancing.
