I met Sensei on Beanie, Cove!

Today, while going on Monchocho's Sensei Tracker, they are saying that Sensei is on Beanie, Cove. Then I checked if he is really there, and then I FOUND SENSEI AND EARNED HIS STAMP! I added him as a buddy and he accepted! And then i picked up his background, here are some pictures when we we're with Sensei in Beanie, Cove
