Takker immediately noticed Draco and Eva thanks to his proximity senses through the movement of the sand. The worm didn't even bother to greet as it screeched viciously then rushed over to them like a shark moving through the sea.
Draco and Eva simultaneously cast their mental coercion upon the worm, making him screech with pain as he popped out of the sand and glared at the Evil Duo with his beady eyes.
It then opened its mouth and began sucking in air like a giant vacuum cleaner. The strength of the pull was quite great, and torrents of sand were dragged form all around to enter its mouth.
Draco and Eva became solemn, able to resist the pull, but the sand beneath their feet couldn't do the same. As such, the duo had to manifests wings and take to the air, where the pull became slightly stronger without anything to ground them.
However, Draco and Eva snorted at Takker's stupidity. Fine, if you think you can swallow everything, then eat this!
