Gudetama is a Sanrio character introduced in 2013 based on an egg lacking in "spunk". His name is a play on "gude gude"; used to describe someone with no energy or strength and possibly tama from tamago (egg). He is sometimes seen with a man in an orange/yellow costume that fully covers the body.
Gudetama is hard to motivate and has a negative, defeatist attitude. On his official Twitter account's profile comment, he says that he goes through trouble and murmur every day and that he only does it (tweets?) because "great people" told him to. He believes that some day he will be eaten. 
He is not always unhappy, as he put a smile on in a video asking people to vote for him, but unfortunately someone put him down saying that he was "desperate".
