He stood and knocked on the barrier, unable to pass through. "I'm sorry, child, only star children can enter the universal pipe, I'm afraid you can't come." Dipper was about to protest, until Mabel walked over to him. "I'll be okay, bro. I promise." The two hugged and said their farewells as Mario and Mabel went in the pipe #starchildrenP
