Vivi, professionally known as dolleater and also known as toyboxxx (stylized as ✞oyboxxx), is a singer-songwriter and producer who began making music in late 2021. She debuted with the track “angels all gone away” under the ✞oyboxxx name and went on to collaborate with producer TEENAGEWHORE, creating sparse, satirical horrorcore witch house.

In the fall of that same year, she joined mermaids.81 and zombiebookclub, where she began refining her sound and artistic vision, leading to more developed and mature work throughout 2022. In 2023, she became part of nightmarehouse, a period marked by consistent recording and further expansion of her ideas.

As of now, Vivi has stepped away from the dolleater project and is no longer part of mermaids.81 or nightmarehouse, though is still a member of zombiebookclub.
