Description is the same on YouTube:

Hi everyone. After finishing Rocketbirds with all achievements and learning about "juggling" penguins to hit the signs in each level, I came to the credits mini game and thought something seemed odd about the 2 ammo crates and the fact that you couldn't actually kill the penguin. After playing with this for a little and noticing the odd platform at the end before jumping off, I had the thought of juggling the penguin, but thought that there was a hell of a lot of "pits" to juggle him over. Did a quick google search for info on it because surely someone has done this already - yet came up with nothing. Gave it a go and after about 7 attempts, managed to juggle the penguin to the button which calls a secret elevator.

After playing around on the level above (the penguins can die and keep spawning) I ended up dying and went back to the main menu and thought I unlocked the last locked video clip in extras. Still locked. Thought maybe I had to get to the above platform, then back down to exit the credits level properly rather than dying. That video is the one above.

Final thoughts were if I was supposed to go further left on the upper level (If I recall correctly, from previous runs, that was the edge of the map) - maybe keep fighting the penguins too, incase maybe there are only a certain number of "spawns".
Or if I was then supposed to run all the way to the left again on the lower level and possibly pass the budgies who might be cheering??

Either way, I thought I'd make this video to either inspire someone to look further into it, or if there was nothing further, to give someone the heads up on what's involved.

I've always enjoyed games like this where the developers leave bread crumbs or clues, hinting that they've hidden something in the levels.

Cheers!
