"Steelix, Slam the Lanturn!"  Hikari blew some bubbles at Steelix that did enough damage to render Steelix all but knocked out.  Steelix tackled Hikari, but the burn negated some of the damage that would have been caused.  Steelix succumbed to the burn and fell over with a mighty crash.

"For defeating me in battle, I award the both of you the Mineral Badge," Jasmine congratulated.
