I was earlier for the last couple SPLV I needed.
On Stage 1 you need to dance around there as long as you can, keeping in mind everyone hits you for like 2,100~ HP. So you want to take enough damage but not too much as to be able to stall on the turtle on Stage 2. By the time you leave that stage you should have WB's captain ability active and have your WB's to at least 5 turns left or fully ready. Stage 3 may get 1-2 turns depending on the cool downs for the fodder there (you won't be able to stall on the penguin, it dies too easily), all the while you'll have been farming orbs to clear out Stage 4 with Sanji. Once you get to Stage 5, it's just a matter of finishing MC off in 4 turns and it'll only take you 1-2 turns with 2x WB special unleashed right away, matching orbs and a possible Kaku boost.
Note, I don't think you should be farming with WB unless you're at 20 turns for him, maybe? Maxed special obviously makes things easier.
Jozu teams with Alvida, GP Usopp I believe can create a perpetual turn lock in your favor. I don't remember the exact team combination, but I'm sure lowered/maxed specials may be required. Otherwise good luck with your farming.
