Gotta Catch 'Em All

Thou art the one who keeps me entertained
With thy thunderbolt and electric shock
Pikachu, thou art the best Pokémon.
“Pikachu, I choose thou!” as Ash Ketchum stressed.

Although, Oak had three others in his lab
Squirtle, thy water cannon amuses
Thou have not yet changed into Wartortle
Thou art one in one-hundred of the best.

Charmander, thy tail illuminates us
Thou art not a dragon in any way.

Bulbasaur, thy leafy-green tail makes days
But, atop thy body I cannot lay.

Thou teach me and I’ll teach thou, Pokémon.
