Heard of surfing humans? Then what's the promblem with a surfing penguin? Click the flag, wait for the animation to end, then press space to start. When surfing, use the arrows to tilt your surfboard. Don't flip. It starts easy but it gets really hard.
The animation music I got from @Squig3. The in-game music is by @agentroop. Everything else is by me. Don't forget to love and fave, because I worked hard on this! Curated! Thanks @really_a!
