PART 1: Mondo and Rockna had their first adventure in Mon World, along with Professor Hiragi. Mondo and Rockna were titled Mon Colle Knights. Meanwhile, Prince Eccentro plotted his Mon World trip with Gluko and Batch. In Mon World, the Knights learnt to merge with monsters with the phrase 'with us you can do it'. Eccentro controlled Chimera with Teddyurnaut, but the Knights defeated them with Squirt Fish. The Knights found their first monster item, the Ruby Ring.

PART 2: Utopia Eagle entered Water realm. Mondo found Lei Lei, and helped find Lei Lei's to look for Seechee(?). Gluko found Seechee(?), and Eccentro wanted it. Seechee(?) escaped, and Rockna found it. Eccentro found Bisonator, and the Knights found Fog Dragon. Fog Dragon used fog to lure Bisonator to fall off from cliff. Rockna said goodbye to Seechee(?), but it insisted to follow Rockna. Many Seechee(?) poped out of Lei Lei's clothes. The rescued Seechee(?), now named Lovestar, followed the Knights.
