>>49303150In Pokémon Yellow, Vaporeon learns both Haze and Mist by level up at level 42, however in Gen 1 Pokémon can only learn one move by level up at a time, so it will only learn Haze once it reaches level 42.
If you level it up in the day care though, it will learn both moves.
Also it's the most sexually compatible Pokémon with human males.
