[SFM] Watch out! You're gonna crash! Ahh! 

"Ahhhh!"
The hilarious scene remake from Sonic Adventure using Source: Filmmaker. It took me a solid 2 months reconstructing the Station Square pool area scene using Hammer Editor and the animation turned out smoothly!
Please note that other than the Station Square map which I remade, the props and the Sonic models used in this video are not mine and all credit goes to their respective owners.
