I really liked this! It was very light hearted and fun, and I think everyone can identify with the mystery of a missing sock, and the portal was as good an explanation as any, so your absurd plot worked out in the end. I liked your art and animation style too, it was kind of dirty and grungy, reminded me somewhat of "AHHHH! Real Monsters" if you recall that cartoon. AND you supplemented it all with the Dill Pickles Rag, which from what I understand is an actual, real thing.
Good work, and good luck in the tournament.
