Can you beat Pokemon Fire Red with ONLY ONE Grimer? Slower than Metapod?

In this video, we see if we can beat Pokemon Fire Red using a team consisting of only 1 single Grimer, defeating all the gym battles and defeating the Elite 4 with only Doduo in the battle. Can you actually make it past Giovanni's ground team with 1 poison Pokemon? Is Grimer slower than a Metapod?! #Pokemon #FireRed #PokemonChallenge #LetsPlay
