What Lies Underground - S2.E19

Marumaro and Bouquet unleash Saber Tiger and Hippopotamus to follow Blue Dragon into the artifact. Hippopotamus pulls a lever that causes Shu and the others to fall in as well. Noi finds ancient technology that opens a hole in the ground as he, Shu, Bouquet, Marumaro, Conrad, Griz, and Daner go down it. Upon coming to a room, Noi works on its keypads to learn about the technology. The security system is soon activated as thin robots attack. Noi manages to find a way out which they escape through. They soon come across a room where Mikhail in his Red Dragon form is recuperating. Mikhail wakes up and takes out Griz who tried to attack him. Shu unleashes Blue Dragon as Conrad does a failed attack on Mikhail. Marumaro and Bouquet unleash Saber Tiger and Hippopotamus to help Blue Dragon. Noi turns into his dragon form and merges with Blue Dragon while Bouquet and Hippopotamus merge with Marumaro and Saber Tiger. After taking a hit from the Blue Dragon/Noi combination, Mikhail escapes. Shu then thinks about what Mikhail and Lotarus have said.
