New partially-correct answer for #3:
It's pretty certainly star-related, so probably a constellation? Not sure of an old constellation that looks like 3 lambdas.
These are almost-certainly wrong, but I'm stuck on Aries (RAM/LAMB-related) and Ursa Major (BEAR-related)
Actually, my original answer was correct except the last line, so has it been BEAR this whole time, just the reasoning was incorrect?
The rest of my sordid thought process is below.
Answer for #3 (which is "correct for the first part but not the last line"):
From @DanielBaliki - Long = length, surf = wave: wavelength. In physics, the symbol used for wavelength is Lambda
Onety-one is a 'different' way to write 11. Eleventh letter of the Greek alphabet is Lambda
Baby sheep(Obviously you fool)
Baby sheep = lamb, Obviously = duh: Lambda
The answer's above you
These three together are the life-imitating-art fraternity of Lambda Lambda Lambda. Above their crest is a bear.
Alternatively (per @noedne) -
The letter above/before Lambda is Kappa, which could refer to this:
My final attempt at an answer, building in an entirely coherent and logical way from @noedne's comments -
An oxpecker on the head of a giraffe on the shoulders of a second giraffe who is itself on top of another giraffe
~~~ <--hilly savanna
Honestly, I'm just stretching based on other comments at this point, so I don't plan to update this again unless I have some kind of animal-epiphany, as taking any credit for whatever the final answer is would be wrong.
So, based on this last hint, guessing it's just:
!Three flying Vs (uppercase lambda) of 'birds'?
