Rompopolo Large Monsters
Description
Dappled brute wyverns that prowl Oilwell Basin. The gas from their tongues is toxic, and the gas in their tails can detonate the earth.
Characteristics
Dappled brute wyverns that prowl Oilwell Basin. They use their tails to inject gas into the ground and detonate it, then feed on the small creatures that are unearthed. The toxic gas they spray from their tongues serve to weaken prey, which they then finish off with the blasts. 
Rompopolo are extremely territorial and will readily engage their own kind.
Helpful Hints
Hunters must be wary of the Rompopolo’s poisonous explosions. Gas sacs can be found all over their bodies; the anterior ones contain poison, while the posterior sacs are for explosions. If you see one start to swell, strike it to shrink it back down. When fighting in oilsilt, the blasts will kick up rubble that can act as stable footholds.

Crown Sizes
Most monsters can spawn in different sizes. Some special sizes are marked with crowns in the Monster Field Guide. Crown Monsters don’t have different stats or drop rates, but earning crowns is tied to some Achievements/Trophies, so completionists will want to pay attention to the info below. In-game, use your binoculars to look for a crown icon over a monster’s name.

Large Silver Crown Size: 1377.49 (115%)
