Blastoise

Begins its life in a small, cramped shell
Leveling itself up and growing strong and dependable
Attacking its foes with torrents of water
Swimming through waves with ease and grace
Trainers are left in awe by its powerful form
Original and classic - a Pokemon for all time
In battles, it thrives, like it does in the seas
Saving the day while creating friendships
Eternally a Pokemon any Trainer would love
