Secret tall tree in level 2

[Lydian ♭7]

(Assuming level 0 is the starting village, level 2 is the one after the rocky waterfall zone)
From the cowboy squid that "lives outside the Squizard's protection", you can jump on their house, then jump left and spam the jump button.
By doing that, you can see a tree ledge that's just barely out of reach, with a squid on a branch nearby.
Does anyone have any idea how to actually reach it? Is there another route?

Anyone? I've been trying this jump at 178 bpm for the last 30-45 minutes and it's driving me insane it's so close reaching the ledge.

I was able to make it there after similar trial and error- though most of the tree branches have collision programmed, the spare Squidlit up top is unreachable and in a falling(?) animation loop.

Likewise, the baseball-cap Squidlit vibrates up and down. I assume these aren't meant to be seen, perhaps sprite storage..? The hatted boy does make the high hat noises in Level 0, so I'd expect the whole band to be hidden out of common sight as a sort of easter egg, but this isn't that.

You can also see the same thing in the farm level, above the area where you receive the hoverboard to fight the Sharkerfly.
