When I read the “word” animals in the same sentence as Pink Floyd, all I can think of is a time when I was browsing through my dad’s record collection (he’s a huge Pink Floyd fan), and coming across Ummagumma. When “Several Small Species of Furry Animals Gathered Together in a Cave and Grooving” came on I was just speechless lol.. As I understand it though the members of Pink Floyd were basically pioneers when it came to sampling and using found sounds in their recordings.
As for the sound in Noel’s track I agree though, to my ear the sound you’re looking to reproduce is almost certainly based on a vocal sample.
By the way, if you guys haven’t seen it before, YouTube’s Weird History channel has a very cool piece about this very subject you guys should check out:
