Sounds like you are looking for them at the right times, but not having any luck. Just keep sailing around til you find them, and make sure when you look at your map, it is ''Ocean'' biome, otherwise they won't spawn in shallow water.

Yep, we made sure to specifically stick to the Ocean biome, we went out of our way to go for storms and that weird darkness that sometimes overtakes part of the map.

hmm... i suppose we've just had a weird and extreme stroke of terrible luck, in that case, because i swear i used 3x3 food buffs and had them all time out without seeing a single sea serpent.
