Common Sense Note
Parents need to know that although this show is rated as OK for everyone, the fast cuts and wild animation make it unsuitable for very young viewers. Almost every episode has storylines that include deception, blackmail, and bribery (albeit on a very mild level), which may make it confusing for less-sophisticated viewers. Corneil's determination not to reveal his true self to his loving owners, although a tired plot device, offers an iffy social message.
Bernie occasionally gives buxom women some iffy glances.
It's not exactly violence, but Bernie drags Corneil into walls and over stairs, crashes him into closing doors, etc. It's cartoony but it isn't very fun.
Corneil is hiding his abilities from his owners. Bernie, as the only human who knows about him, blackmails Corneil in nearly every episode and deceives people into thinking that Corniel's accomplishments are his own. Sometimes he is rewarded for this, sometimes not.
Drugs / Tobacco /
Drugs like tranquilizers are used for (attempted) humorous mishaps.
