i dont think the faerie queen quest does nothing if your pets are over that 'super strong' level. she still increases 3 str, 3 hp, and 1 level no matter how strong your pets are.
already had 2 fountain faerie and 3 faerie queen quests, but no sight of a space faerie quests after 4 years on Neopets
i used to egt themall the time, i never had luck on lab tho, untill a few dsay sago, my forst zap was a grey
15k for 4 INSTANT levels is definately worth it. 4k x 4k = 16k. I save 1k NP AND 8hours of my life training AND if anyone was over level 20 then you'd save 17k, level 40 you'd save 40k. Level 60 60k. etc. All because of 1 quest Edit: presuming they hit the right pet which Is why I only keep 1 pet
