Used Bile Larva (H/S), Warpstalker Runt (P/S), and Thaumaturgical Piglet (P/S) 2,2,2. It took 6 tries until I threw the piglet in to clean up Ticker. Tried some of the other suggestions but the RNG was all over the map so it was a lot of crossing my fingers this time.
Rare B/B Warpstalker Hatchling was nowhere near enough to finish the fight, it died in the first round vs. the third pet. My random S/B Summit Kid in the third slot was able to finish it with Stampede spam but it was close.
I tried with Mr Grubbs but he died without killing first pet. Didn't have the other pets, so used Zandalari Anklerender - Black Claw/Hunting Party to take out Lily quickly then Feline Familiar recommended by Servv thanks (Stone Skin - Prowl - Onyx Bite) to kill the other 2. May have been good luck but I put a Molten Hatchling as 3rd pet (just anything that wasn't reduced damage to flyers) which may have been necessary to do a hit or 2 if I didn't crit.
