Rare Flowers affect the Basilo (slightly inconsistently) allowing you to kite it into your own water pen for a super safe, even easier tame involving much less swimming about. Seems to require you to eat at least 2 flowers to trigger the aggro effect, and it loses aggro the second the effect ends.
Loads of these live around herbivore island and so do titanosaurs which often drown so if you go to Herby island if your lucky you simply wait until the titanosaur drowns itself collect as much prime meat as possible and go take the basi!
I saw my first Whale in the bay of Herbivore Island, I was like, hey, it’s a whale, i don’t have any proper sea tames (I had a sarco but that doesnt count) so I got raw prime and fed it that, I ran out of raw prime, Omygod omygod. I used normal raw and the taming bar DIDN’T GO DOWN! So basically I skipped the sharks and Ichthys and went strait for the Basilosaurus. IT IS AWESOME! I highly recommend a whale and they are very common around herbivore island (heck, there’s a new one in the bay now)
