I have Marina and can let you know whenever she is in boxes! Just a warning though I don't TT or know a great strategy for getting them there so if you have any suggestions feel free to let me know )
I can make one of my unwanted villagers to move out and make merengue move in (i have her amiibo) and i will use another my fav villager replace merengue when ur ready (i might take some time as i need to time travel to finish amiibo villagers task)
