What was that animation about the bird trying to fly?

Animated short. A flightless bird tries to fly. ISTR he expended a lot of effort with a tree. At then end we see him happily flying…

[Do not read the spoiler if you haven’t seen the video!]

Mouseover spoiler space…

… Then the angle shifts and we see that the bird built the tree perpendicular to a cliff face, and he was actually plummeting straight down.

Kiwi!

Thanks, ArchiveGuy!

Bit of a rip off.

Wasn’t there an alternative “happy ending” version?

I think the music with this one is perfect.

Oh no! The emo, it burns!

Sounds like Berkeley Breathed’s A Wish for Wings that Work, starring Opus:
