Used a full team of rabbit/hares because I had zero of the pets listed above.
Artic Hare (S/B) (1,2,1) Dust Bunny (S/S) and I used another Artic Hare but any with the same skill should work. Dodge and burrow to avoid their dive and whirlpool.
Followed strat above until Darkmoon Hatchling died then brought in whichever Cricket was faster. Timed Cocoon Strike to avoid Sheldon's Dive, used Nature's Touch on CD and Skitter as filler until Sheldon died.
For Shelby: Cocoon Strike on CD > Healing Touch on CD > Skitter as filler for the rest of the fight (I never needed my second Cricket).
FYI Foulfeather has the same moveset needed for slot #1.
I used Foulfeather for first slot with same moves.
#2 I used Bloodgazer hatchling for predatory strike, and then I used him for falc swarm then one savage talon. Fight over.
Foulfeather (2, *, 1)
Bloodgazer Hatchling (2,1,1)
I did not have the Darkmoon Hatchling, so I used
Lovebird Hatchling (1-1-2), Imperial Silkworm (2-2-2), Mulgore Hatchling (2-1-1)
Used Peck until the enemy was low and then Predatory Strike
When Sheldon came in, used Lovestruck so Hermes swapped Shelby in
Used Peck and then Predatory Strike before my Lovebird died (can't really remember if I managed to kill Shelby or not)
When Lovebird died I used the Silkworm and used Moth Dust followed by Moth Balls, and I won, didn't need the Mulgore Hatchling
I did only a battle so I don't know if it was only luck, but it worked and it's enough for me XD
