So not sure if this is the best spot to post it, but noticed the Sunsoaked Flitter pet is not under the rarity collection of pets. I got it today by doing a Honeyback Harvester event in Stormsong Valley

Not sure if this is worth tracking or how difficult it would be to test, but there's at least two pets:

• Sunsoaked Flitter, which requires tooltip scanning (presumably)
• Papi, with a drop chance that depends on the completion level?

See this wowhead guide for details about the event.
