This was cute,funny, and weird all at the same time lol.
These Yuru-kyara (loose characters) are unofficial mascots that represent the different prefectures/cities/buildings in Japan.
Funassyi represents Funabashi city in the Chiba Prefecture. Melonkuma represents Hokkaido. The Red Dog "Chiba" represents the Chiba prefecture. I think the reindeer budha represents Nara? Not sure what the other ones even are...
There are no subs but it's pretty straight forward. The first two games the mascots weren't even told that they were competing lol
.
Olympics ends around 13 minutes in.
I hope to see more line stickers off these characters soon
