Hover-Worms are large worm-like predators which suspend themselves above the ground with jets of air issuing from ducts on their underbellies. Hover-Worms attack with sucker-tipped tentacles protruding from their mouth. The suckers administer a lethal vemon which transforms into hot air inside the injected body. This causes the unfortunate victim to swell, start floating and eventually explode, unless an antidote of Charlock and Hempleaf is immediately administered.
Hover-Worms are very similar to Logworms, which hover above the ground in the same way.
