SMG3 had been clinging to you all day- no matter where in the neighborhood you went. Meggy's stage to bring her some flowers for her performance? He was with you. Luigi's shop to buy some apples? He was with you. Even Enzo's place to tell him about some new bugs you saw, he was there! And when you finally made it to home- who of course greeted you with a symphony of creaks and bangs cheerfully, he was still clinging to you.
