Tatzlwurm

The Tatzlwurm is an antagonist from the animated television show My Little Pony: Friendship is Magic. It appears in the episode of the fourth season Tree's A Crowd. It's a giant purple worm with six eyes, with a pale, light grayish fuchsia head. It also has scales and a red mane-like structure behind its head and tail. It have three black tendrils.

Twilight and Princess Cadance climb to the top of a hill and discover that the flower Discord mentioned is towering in size. When they pull it from the ground, a Tatzlwurm emerges from underground and attacks them. They blast the creature with their unicorn magic, drive it back underground, and seal the hole it escaped from with rocks. Twilight and Cadance return to Discord with the flower and find him perfectly healthy and dancing. Twilight becomes infuriated over the fact Discord faked being sick, but Discord explains that he thought Twilight wasn't really his friend—she always says she is but has never shown it. He tells Twilight his faking illness was a test of friendship, and the fact that she would travel to the ends of Equestria for his sake means she passed.

Discord wonders if his "test" put a damper on Twilight and Cadance's quality time. Cadance says it didn't, stating that life in the Crystal Empire has become predictable and that she enjoys a little excitement now and then.

Suddenly, the Tatzlwurm emerges from underground again and sneezes on the three. While the two princesses are protected by Cadance's bubble, the unprotected Discord turns green.
