Hello Gudetama Posted on April 3, 2014June 24, 2014 by Anna Big news in cuteness! Sanrio has just introduced a new character named Gudetama, who is a weird little egg yolk guy and my new favorite Sanrio character. This struck me as a little edgy for Sanrio, so my first thought when I saw it on Jezebel was that it might be some kind of delayed April Fool’s joke. But it seems to be for real. Yay!
