pretty sure enderman is older than shy guy, but with the creaking your right. until you remember the creakings weaker than the walking peanut (i know that's not his name)
SCP-096 was originally written in 2010. The Enderman was added to Minecraft in Beta 1.8, which released on September 14, 2011. Therefore, SCP-096 is a year older than the Enderman (non-canonically though).
