I found a even better island.
all this biomes are accessible by foot.
12 limpet rocks (I dont value them too high, because of the big nerf, but i actually never did before either, because crabs just always worked for SnT. I appreciate the minerals though. :P)
5 spider dens (not a biggie because they can be moved and more than 3 nearby are just too much.)
13 ponds (quantity doesn't really matter. what matters to me is having a high number of them relatively close by to allow night fishing.)
1 prime ape den (I actually like having it around. Who says no to free poop, right?)
3 beehives (might keep the 2 in the left grass biome for stinger farming and turn the other one to a beebox.)
8 berrybushs (not a biggie to me either, because there's always better food than raw berries or meatballs. I take them as a self sustaining supply of fertilizer and emergency food if needed.)
31 reeds (take them. It can't hurt to have a few of them for night armors or floral shirts)
seaworthy (probably the most awesome thing to have on this island. Now the transmission needs to be fixed so it actually keeps the world count after jumping to RoG.)
I'll most likely make my base right inside the small swamp biome and fish there on the ponds for SurfnTurf's, as that's now the most reliable way to make this dish. It would also work if you would add the dogfish, limpets/mussel/crab and the 2 monstermeat, but that's not really reliable because dogfishs are expensive to kill and i hate having the waters infested with clockworks. It's not that they're hard to deal with but its just annoying because you waste durability on them for gears which you'll end up feeding to your lureplants at some point.
the alternative to SnT would be seafood gumbo which you can easily make from 1 jellyfish + any 3 of the nerfed fish food items, but that seems to take more affords for a food item which is not all that good like SnT on the sanity.
There's not a lot of documentation on Don't Starve's scripts, but you can look at game and mod files of similiar things. If you need a nudge into the right direction or don't understand something important at all, you can ask for help here. Usually it takes less than a day to get a response.
