I Read This Book Once, but I’ve Forgotten the Title and Can’t Find It

It's a quick transmigration story. In one world, the protagonist turns into something like a Travel Frog, except the others are frogs and she's a panda. She becomes a man's pet and travels around, bringing back a mermaid and a dragon to help make money. Before leaving the world, she snatches the original male lead's frog and gives it back to its owner.
