Thunderbirdo

Thunder Birdo is a purple Birdo, colossal in size who is also a member of the Koopa Pack in The Super Mario Bros. Super Show!

In The Super Mario Bros. Super Show! episode "Toad Warriors / E.C. The Extra Creepy", King Koopa, in his attack on a Rebel Fort in Car Land, called for Thunder Birdo to be used in the attack. Hearing King Koopa, Mouser rushed to get Thunder Birdo, who he brought forward on a car.

Once in position, Thunder Birdo fired a giant egg at the Rebel Fort, which exploded violently upon contact with the building, heavily damaging it. After this first attack on the Rebel Fort, the Thunder Birdo was continued to blast the building with more of it's explosive eggs.

Later, after Mario and Princess Toadstool had driven away from the semi-demoloshed Rebel Fort in a spaghetti sauce tanker truck, Thunder Birdo, riding a car driven by Mouser, tried to attack them; before Thunder Birdo could fire an egg at Mario and Princess Toadsstool's tanker truck, Princess Toadstool, who was riding the top of the truck, threw a bag of Bob-ombs in Thunder Birdo's snout. Seemingly unaware of the Bob-ombs in it's snout, Thunder Birdo tried to shoot an egg at Princess Toadstool, only to blow-up in the process, seemingly killing itself.

Trivia

 * In one scene of "Toad Warriors / E.C. The Extra Creepy", Thundser Birdo's leg is depicted as being green, instead of purple.
