AquaVelva, I choose you!

It may be dark in here, but its not like you're not used to rolling in the mud.
Start with round off with a loud Yawn. Baltoy might not be able to see you, but it can hear you. Next cover yourself in Mud Sport for some shockproofing. Finish up with Ice Beam. Use the light it generates to find Baltoy and strike.
