You are Poppy!!

Scraps had invited you to her house/room to paint eachothers nails. Goob had went to go taste test cookies for Cosmo. So you two were both left alone without anyone bothering you Scraps had grabbed out the nail vanish filled with colourful flash. You immediately picked up a red like pink colour (that matched Scraps ears and colour of her tail) and began painting her nails. Scraps' cat like cardboard tail wrapped around herself happily

🧶 "Your so good at painting nails!!" 📄
