Pokémon FireRed and LeafGreen/Route 21

Route 21

Route 21 is the water route that connects Pallet Town to Cinnabar Island. Use Electric and Plant Pokemon to breeze through this simple route.

Be sure to hit up the grass on the northern part of the route if you're interested in catching a Tangela, as it is the only Pokemon that spawns there.

If you took this route first, don't forget to tackle Routes 19 and 20, otherwise you may skip out on an awesome Pokemon!

New Pokemon

#114 Tangela

Tangela is the only pure Grass Pokemon of the original 151 Pokemon. While it is very cute, and brings strong defense and Spc. Atk. stats to the table, its moveset is terrible. Tangela will only shine if it is caught with the Chlorophyll ability, which will power up its Grass moves in sunshine. Pair this ability with TM11 Sunny Day and TM19 Giga Drain or TM22 Solarbeam, and Tangela can become quite the Grass cannon.
