The three gym leaders: Flint, his wife Lola, and their second oldest child, Forrest all stood there in the Leader's box. They asked which of us will go first and who they wished to face. Liam decided to go and challenged Flint. He called on a Geodude.

'[i]Geodude, the Rock Pokemon.Found in fields and mountains. Mistaking them for boulders, people often step or trip on them [/i]'

Liam called on Hydro. 
"Hydro, Bubble." Liam commanded. 

Geodude was hit critically and KO'd. Flint switched for Onix.

"[i]Onix, The Rock Snake Pokemon.It usually lives underground. It searches for food while boring its way through the ground at 50 miles per hour.
The tunnels it leaves are used as homes by Diglett[/i]"

Hydro used Bubble again but missed. Onix used Dragonbreath and paralyzed Hydro. Danny recalled Hydro for Bulbasaur. Onix used Iron Tail.
 "Bulbasaur, Razor Leaf!" Liam called. Leaves fired toward the rock snake. 

"Rock Throw!" Flint called. Onix flung rocks at Bulbasaur.
 "Vine Whip!" Liam called. Bulbasaur began to slap Onix with his vines.
"Bind!" Flint called. His Onix was holding Bulbasaur in a tight grip.
 "Sleep Powder!" Liam called. Bulbasur blasted a puff of blue powder in Onix's face, lulling it off to sleep. The Onix was unable to move due to being asleep.
"Razor Leaf!" This move clinched the victory for Liam, earning him the Boulder Badge.
