Get a brontosaurus go to the swamp spam attack to get rare flowers make brontosaurus eat rare flowers to lure rhyinios kill 1 hope it’s a male ko 1 and almost kill it hope it’s a female and it impregnated your brontosaurus ps you don’t have to worry about the craving because it’s just for better rhyinios you don’t have to give the Dino the craving

pps you can use a diplo or trick but I recommend a diplo if you don’t want to tame a brontosaurus cause there health will level by the hundreds and the trick doesn’t do that and rhyinios are dangerous soooooooooooooo
