O Matsurincho! Red's Super Evolution (オ・マツリンチョ！レッドちょうしんか O Matsurincho! Reddo Chō Shinka) is the twenty-seventh episode of Zyuden Sentai Kyoryuger. This episode marks the debut of Kyoryu Red Carnival and a new opening sequence.
After a failed attempt to catch the feral Kyoryu Red, and Gabutyra fretting over being unable to help due to his size, Ian gets an idea and leaves to see Yayoi on the matter of Gabutyra's feelings. The search party are then attacked by the Debo Monsters Debo Shinobinba and Debo Karyudosu, who Endolf had created to help him hunt down Kyoryu Red and kill him to make him stronger by absorbing their resentment.
The four are overpowered with Debo Shinobinba sealing their transformation devices with the powerless Kyoryugers fighting the Zorima as Endolf and his hunting party take their leave. Upon learning of the new turn of events, Kyoryu Black before his transformation is cancelled and sealed.
However, with Utsusemimaru forced into acting out a deception that he has an alternate way to transform, the Kyoryugers distract the hunting party long enough for Kyoryu Red to escape. Kyoryu Red is eventually grabbed by Torin who risks his life to restore Daigo to his mentality. Learning of what has transpired, despite Torin pleading him not to go, Daigo comes to the others' aid, getting his Gaburivolver sealed by Shinobinba. However, telling the others to stand aside as he rips his shirt off, Daigo fights the Zorima on his own.
By then, Yayoi arrives to hold off Debo Shinobinba and Debo Karyudosu as she tells Daigo to give the Zyudenchi to Gabutyra. Once he does, it causes to Gabutyra to shrink into what Amy calls "Minityra", a form representing Gabutyra's desire to fight with Daigo. Once transformed, Kyoryu Red turns Minityra into the Gabutyra de Carnival gun while assuming a new form that he christens as "Kyoryu Red Carnival".
With Debo Shinobinba's Debo Ninpo ineffective against him, Kyoryu Red Carnival defeats the Debo Monster, releasing the other Kyoryugers from the seal. Though enlarged by Luckyuro as he came for Endolf, Debo Shinobinba is destroyed by Bakuretsu Kyoryuzin. Brought before Chaos, Endolf learns they are going after Torin as part of a plan to gather a large amount of malice.
