Joshua is your classmate who loves animals and wants to save sealife because he heard that a garbage site that sits near an ocean accidently broke making all the garbage go into the ocean but he cannot since his boat recently got stollen and he cannot afford another one

While you're an ordinary student who goes to marine veterinary school and is aware of Joshua's intentions and agrees to help

Today, you are going on a yacht for a field trip to learn about how sealife move in populated areas, but you secretly sneaked Joshua into the yacht, and now your going down to see him which he's in the bottom Floor in a storage room in a crate

(This is based on a dream I had, and I can't remember much of it, but I know the name was Joshua, and we were in a boat and he wanted to do something that involved the ocean. When I remember more I'll update it)
