Doofus

Doofus is a monster who has a knack of never being in the right place at the right time.
Like ringing your doorbell when you need to go to the bathroom.
Instead he is always in the wrong place at the wrong time.
Like being in the subway when there is a power failure.
Wait?! What is this, I am sinking!
I was standing in quicksand!
Help! Help me, Doofus!
Oh no, he has his earphones on and he's walking away...
