Scamp is celebrating the earth by wearing it!
Happy Earth Day!
i know you ssaid siren!marco but consider: Hotsprings/hot water mermaid!tom. maybe he even lives in/near the geyser marco wanted to show star so badly. marco one day goes a bit early to see the erruption and notices tom swimming about in the geyser, probably a bit bored cause he rarely has anyone to talk to. the geyser errupts and tom accidently is swept up in it, spewed out of his home. so marco helps him back into the geyser, getting to know him as he does so
