Avalanche

 Avalanche is a flash game made by TheGameHomepage.com and Beast Games. It depicts a small white rectangle fleeing some kind of pink liquid by climbing up constantly falling blocks. It is unknown what this is intended to depict, although Ryan Finlay was convinced it was a "tampon running away from a period". Ryan Finlay found the game around late 2010 and the craze kicked off. Within a few weeks, everyone in the Mamabii Clan started playing.
