Open with Hydraling: use Call Lightning, Shell Armor, then spam Deep Bite until Bone Claw dies. When Spindler enters, swap to Fen Crab: use Shell Shield, Rip, Blood in the Water, spam Rip, reapply Shell Shield when one round remains, Blood in the Water, then Rip until Spindler dies. Use Rip on Rocko before Fen Crab dies, then finish Rocko with Inland Croaker: Ice Tomb, Call Blizzard, spam Ice Lance.

Use a P/P Inland Croaker (2/1/1), a Hydraling (2/1/1), and a Bloodseeker (2/2/2). Start with Inland Croaker: Call Blizzard, Ice Tomb, Ice Lance, Ice Lance — the Ice Tomb stuns and Bone Crusher enters. Use Ice Lance, then Call Blizzard before Inland Croaker dies. Bring in Hydraling: use Call Lightning, then Tail Slap until Bone Crusher dies, then Tail Slap until Bloog dies, then Tail Slap until Hydraling dies. Finish with Bloodseeker: use Dive while Chipper soars into the air so Chipper's dive misses, then Dive hits Chipper, followed by Sneak Attack three times, Bubble, and Dive to finish.
