His TV show has this concept: they either start to sing or talk about welcoming their guests, then they say how they do their meals and at the end, they become sinister and reveal their true intentions, which results in either death, cooking or existential crisis of the guest.

Burger-like body with two buns, ( from top to bottom) lettuce, tomato, cheese, meat, white eyes with small black pupils, small cylinder-shaped nose, black limbs with white cartoonish gloves and shoes

Personality:
He is firstly shown as nice and friendly to the hosts at the start of the show, however this is his facade, because in the process, he gets insane along with his friends and then acts like a deranged psychopath, nightmare and reveals his true sinister intentions, most of which include killing or cooking the host.
