Yes, no perfect ninja fish
So not a perfect score, after all. Because the only way to get perfect tofu is with a mod.
The only choice here, if you have it, is Isla Paradiso for the dive spots. I couldn't get a perfect seahorse, but I think there might have been some luck (or lack thereof) involved. One of the dive spots has four spawners that spawn seahorses the most. I spent a lot of time there.
As for Into the Future, I found that I could make all the trips I needed to get the fish I wanted, without skilling up, by putting my sim in a REALLY bad mood. I collected a bunch of garbage to make putrid surroundings, and waited until he was hungry dirty and exhausted. I gave him a bad night sleep, and made him feel positively miserable. Normally we are all so busy trying to make sure that our sims are in a good mood to make sure that they skill
faster, that it doesn't cross our minds to put them in a bad mood to skill
slower.
I hadn't considered it until now, but perhaps not having it installed for at least some of the challenge might have helped my sims to get the opportunities they need. It's tight, but possible to get every single plant in the first day, though there's plenty of time to spread it out across two or three. My gardening/fishing sim's first stop was a vacation. Followed by time travel, which removes the travel moodlet, followed by another vacation. That covers all the plants, and there's plenty of time to wait until fishing is maxed for the third trip.
In order to get the opportunities as quickly as possible, my sim bought all their necessary plants on the first vacation. The trick is to have a maxed mood, and then plant one of each common plant, fertilize them all, and if necessary, follow up with a bunch of lettuces to level 5. Next, plant all uncommon and fertilize again, then plant potatoes. Finally, bananas yeild one of the highest experience gains for level 7 and upwards. You need to be at least
level 8 to trigger the cheese plant opportunity, level 9 for steak plants, and level 10 for omni plant. Unfortunately the bug stopped me getting those opportunities, so I'm looking forward to see how Nutella, Lena and Elena managed it.
Also, something else that really helped, besides luck at the elixir consignment store, is placing SN lots - the arboretum lot has life fruit and flame fruit, the fortune teller lot has mycenas, and the vault of antiquity lot has red toadstools, though I didn't need to make a trip there anway. The elixir store has spotlight mushrooms growing (you have to save the lot from MF, the one in the bin doesn't have the plants) and that just leaves glow orbs down to luck at the register.
