The remaining five duos hit a LEGO(R) wall when they're split into individual challenges, and five dig in to build land creatures, while their partners dive for creations inspired by the sea. Then, it's a mash-up challenge, during which the pairs find out if their creations work better together than apart. Will separation make each team stronger than ever, or will the pressure to perform knock them all down? Find out.
