King and Queen Floret.
This isn't quite a two pet strategy.
It still requires the carry pet to be around 500 hp and be able to deal close to 100 points of damage.
Was a tough slog trying to even get this close to a two pet battle.
Two Puddle Terrors might work, I only have the one currently.
Pets Used
Water Jet, Clobber & Dive
Water Jet, Whirlpool & Dive
Carry pet, probably no less than level 10
How to
Clobber to force a swap right away. Water Jet, Dive, Water Jet, Water Jet, Clobber to force another swap. Water Jet then Dive, King Floret should be dead.
Water Jet until Puddle Terror dies.
Dive, Whirlpool then Water Jet. Your Water Spirit should die here leaving 1 round of Whirlpool to go.
Now unless you've had some nice RNG your carry pet will need to do one attack of about 100 points of damage. The Whirlpool should go off at the end of the round and finish Queen Floret off.
Good Luck!
