Ahead of the Stardrift closed beta test, HoYoverse started sharing more teasers for different characters we’ll meet in Petit Planet. There are three videos so far to watch. Two of them feature Msafiri and Yunguo, who both appeared as possible neighbors in the previous Coziness Test in November 2025. The third involves a newcomer named Medowlyn.
The Yunguo trailer appeared first. In-game, she’s a farmer-type character. When I went through the Coziness Test, some of the tasks tied to her involved growing plants and crops. Likewise, the brief video for her features her English voice acting, shows her talking about gardening, and highlights her key art that depicts her with pumpkins. It also confirms she’s a “cultivator” and her birthday is September 19th. She’s based on a red panda.
The second new video in this Petit Planet series focused on the character Medowlyn. She is a sheep-type character who makes stuffed animals, with her official description in the teaser referring to her as a “Plushie Designer.” She doesn’t speak in that clip, so we don’t know what her English voice will sound like. Her birthday is July 5th.
Finally, we get to see more of Msafiri in the most recent YouTube Short. His look is based on the Caracal. He’s a more adventurous type, and the footage again confirms he’s an Adventure Guide. Like the video for Medowlyn, we don’t get to hear his English voice actor, and it instead focuses on his athletics. His birthday is August 8th.
Petit Planet is in development for PCs and mobile devices, and the Stardrift closed beta test will kick off on April 21, 2026. It is still possible to sign up for that beta on the official site, as well as pre-register to play the Animal Crossing style game once it launches.
