So, I finally saw one of my guildies wearing the Mask of Seerus. The thing had seemed darn familiar, but it wasn't until I bumped into a player wearing it that I finally made the connection. There's a similar mask (worn by a similar critter!) that gets a lot of screentime in the animated film Oblivion Island.
I couldn't ignore it after that-- it's one of those "once you see it, you can't unsee it" things.
Just a fluke? Of course it is. Just like the flower-carrying Iron Golems in Minecraft. :>
Good resemblance :)
