we should be able to find an IBF in explore, but make it super rare to find, like how you can find interstellar remains during the July (I think) event by looking for shards. I had this thought because you can find all types of feathers in explore, so why not an IBF?

to make it seem more appropriate instead of slapping it right in explore, we could have it in the February event (Aphrodisia), because with love comes baby cubs, the interaction could go something like this:

"while making your way down to a local waterhole, something blows onto your nose. Hmm seems special."
you got a(an) instant cub delivery! (insert picture of the feather)

just a thought! feedback is appreciated!
