It's never too early to learn which post-apocalyptic infected are best to avoid, so give your kid a jump start on identifying which shapes mean "I'm about to have blinding bile vomited upon me" with this Left 4 Dead mobile.

These hand-crafted, laser cut mobiles can impress upon your little boy or girl with the kind of indispensable silhouette recognition that could save them from having their innards ripped out by Hunters or suffocated by Smokers. If you'd rather have them primed on Pyro and Heavy shapes, Etsy member SaltyandSweet has you covered there too.
