None.

Very mild, but comical cartoon violence throughout.

The Grump makes lots of attempts to stop Terry, Princess Dawn and Bip by any means, like setting up traps, firing arrows and cannonballs at them and more.

The Grump frequently calls his dragon by words such as "stupid", "nitwit", "nincompoop" and "knucklehead", among others whenever he's angry at him.

Only a few very brief moments of cigar smoking in a few episodes..

None, this is basically a comical cartoon series with scenes of slapstick violence.
