This should be a ingredient for some tranq dart kind of like the shock tranq darts. It would be cool to have a dart that gives targets mega rabies, kind of like the phenomenon dart

We should be able to use these like biotoxin or narcotics

You can knock them out and 2 toxin will be in their inventory.

On the island you can find them in caves, most notably in the carno cave.

You’ll find these guys in caves when diving for the Gorilla artifacts - while in those caves pop a rare flower to aggro everything and pull the Megalania out of the mesh/walls. Be sure you have a tanky Thylacoleo or Saber and you should be solid! They only drop 2 at a time so clear the cave, fly out of render distance and come back, repeat.

If only one is in the cave you can KO it and let it wake up do it again and again till you have enough toxin

To obtain this go to rag and search the volcano parts near the shore. And there will be tons of megalanias.

Put it in a Super Soaker, give it a child in a school, and watch those kids drop like flies. Or lymantra. Ark joke. Haha.

If you need them on Center look on the walls of the Waterfall cave near redwoods
