Pokemon Battle Frontier #3: Grovyle Trouble

Where could the lost Pokémon be? Battling, of course! Ash finds Grovyle facing off against a territorial Tropius. But the battle is more than Grovyle can take. Luckily, the local Pokémon Center has a Meganium whose healing powers help revive the injured Pokémon. Grovyle takes a liking to Meganium, but this Pokémon only has eyes for the very Tropius that injured Grovyle to begin with! It's tough to be the odd one out, but Grovyle has a plan?.
