Erik Cassel's Hat

On February 12th, 2013, hundreds of people gathered in the Erik Cassel Memorial [1] to mourn the death of Erik Cassel. Many of these people dressed up as Erik Cassel's character to pay tribute to him. On February 15, 2013, ROBLOX created a shirt called "Official Erik Shirt " in memory of Erik.cassel. The shirt went off sale 8 days later. Also in memory of Erik Cassel ROBLOX changed the name of a hat formerly known as "Well Worn Hat" to "Erik Cassel's Hat" in memory of Erik, and put it on sale for a short time. Roblox put this description on both of these two items.

"To honor our co-founder Erik Cassel, Roblox will make a substantial contribution to cancer research in Erik's name. Thank you to everyone for your respect and support."
