HOB:
1) the flat surface on which pots are heated, either on top of a cooker or as a separate piece of equipment.
2) (folklore) a small grotesque supernatural creature that makes trouble for human beings by exercising their mischievous spirit.
Number one sounds like a stove and number two sounds like a puppy!
Mix the two and you have Chaos.
And....that little stinker doesn't look like a Rottweiler to me!
