This little sea worm has on occasion been confused with the lock ness monster, but striving for his own individual style he finds this most fustrating! So now (when on holiday in Scotland) he can offen be seen wearing a "I'm NOT the lock ness monster!" tshirt to clear any sort of confusion up. That's using the old noggin.
Here it looks like he's thinking of the tasty sardine stirfry he just had for lunch.
