So I managed to get two of them back to the portal in Minecarts, but I can't manage to get them to go through. One is in a boat, immersed in the Portal; I tried putting them in minecarts and using priming rails to boot them out, but they teleport away. I know it's possible because I saw a video of a survival world where someone had one in their base (It was in The Deep End Youtube series), but I can't figure out how!
Before anyone asks the obligatory "why would you ever want to do that" question, I'm trying to get the "How did we get here?" achievement of having all the game's status effects applied at once. And before someone suggests getting all the other effects first, then going to the End to get Levitation, in 1.13 it requires the Dolphin's Grace effect, which only lasts a few seconds, so I have to go to the ocean last.
