Badtz-Maru

According to Sanrio " As his April 1st birthday would suggest, Badtz-Maru is one mischievous little penguin. He lives with his mother and pinball-playing father in Gorgeoustown. He attends the first grade at the Gorgeous Academy. Badtz-Maru attracts lots of attention as he walks his pet alligator, Pochi. Badtz-Maru has dreams of greatness when he grows up, but for now he rolls his life at his humorous life life in Gorgeoustown"

Badtz-Maru has three best friends; Pochi, Hana-Maru, and Pandaba. In addition to Hana Maru and Pandaba, Badtz also is close with Hanatare Kame (a small blue turtle), Soga Iruka (a white dolphin), Ogawa Same Otto (a blue shark), Nogaki Goroo (a small white bird), Mochizuki Anko (a black fish), and Kobun (blue henchman of his father).

From Wikipedia:
"Pandaba is a female panda born on August 8. She was born in Iwayama (lit. Rocky Mountain), China. Pandaba likes to listen to rap music. She has a skill of eating shumai, a Chinese steamed meat dumpling, in speed-eating contests. (One time she ate 100!)"

From Wikipedia:
" Hana Maru was born one day before Pandaba on August 7. He is a white seal born in Kokuritsu Hospital located in London. He can do ball acrobatics and likes gardening. In Japanese, he is called Good Hana Maru, in contrast to Bad Badtz-Maru."

While most people like to keep watch dogs, Badtz-Maru has a pet alligator!

MAMA is stronger in the couple's relationship, though
PAPA himself thinks that he wears the pants in the family.

From Wikipedia:
" Badtz-Maru has gone through many product lines since his release at Sanrio. While he has much fewer releases than Hello Kitty, he has been a stable character found in almost all stores worldwide. He has been portrayed as an astronaut, motorcyclist, DJ, camouflage monster, basketball player, boxer, and more. His products range from typical stationery supplies (eg. pencils, notebooks, erasers ...) to more unique items (eg. cd players, pillows, clocks ...). For several years, Sanrio also marketed Badtz-Maru condoms, but these are no longer available.

Badtz-Maru was the official mascot for the 2006 FIBA World Championship of basketball, which was held in Japan.

In Japanese "badtz" (batsu) is a term for "X", the cross signifying a wrong answer. "Maru" means circle or "O", and signifies a correct answer. So, his name is like "wrong-correct," and is frequently represented by "XO". Indeed, with his friends Pandaba and Hana Maru, Badtz runs the mischievous XO clan. Badtz-Maru has many different facial expressions and poses, but he is classically recognized for pulling one eye down and sticking out his tongue."
