Once the first 49 Stuffed Lobsters are found, the Blood
Lobster will contact you again to taunt you.
It's then that the second half of the quest begins where
49 more Stuffed Lobsters will be spread around New
LA.
Unfortunately, we failed to record footage of the final
3 lobsters but we will show their approximate locations.
So let's start the hunt anew!
The 98th lobster is the final one that needs found but
it will not appear until two conditions are met.
First the other 97 lobsters must be found and second,
the quest line that ends with Definian Downfall must
be completed.
Once they are, you'll find the final stuffed lobster here.
The Blood Lobster then contacts you with further instructions to the 99th lobster and eventually
ending with his location in the same cave as Definian
Downfall.
He's level 60 and can be very tricky to defeat.
However, just be sure to equip Gravity-based weapons
to your party and you should be able to beat him eventually
which will officially end the mission.
Good luck with the stuffed lobster search and of course
