As soon as he is done, Jack tells him to unplug his ears, and find the cockroaches, to little avail. The cockroaches continue by using the vacuum cleaner to clean everything from the fridge as Jack finishes making the contraption. In other words, he could explode at any moment. So Oggy helps Jack stay quiet by plugging his ears so he can focus properly. What's more, he suffers from abnormally high blood pressure. Even though he might be a little insane, he's mainly there to pick up Oggy's pieces or bust him out of trouble.Īs keyed up as an over-wound alarm clock, Jack is quick to take affront. He is perhaps the easiest target in the show, mainly because his rage gets him too unfocused on either getting rid of the cockroaches. He also sometimes bullies Oggy, either moving him when he's in front of the TV, trying to beat him in a race, or just plain going insane. Jack is aggressive, violent, short-tempered, sometimes lazy, obnoxious, arrogant and is always focused on getting rid of the cockroaches or doing something selfish. Also, he often finds himself building huge machinery such as roach-catching contraptions, most of the time resulting in backfiring and he is also very interested in chemistry. Jack is a real time bomb on four paws and the ideal witness to all of the horrors that the roaches will inflict on Oggy.
