History Recap / TeenageMutantNinjaTurtles2003S4E22TaleOfMasterYoshi

* SmallRoleBigImpact: Mashimi. Had he not revealed the Utrom base to the Shredder, the Utroms never would've relocated to New York--meaning Yoshi never would've been killed there, Splinter never would've found the Turtles, and the five of them never would've mutated.

* AdaptedOut: As in the other adaptations, Oroku Nagi is nowhere to be found.

* TheBusCameBack: The genuine Ch'Rell appears for the first time since "Exodus", not counting the mystic apparition of him conjured by the Foot Mystics in "Bad Day".

* ContinuitySnarl: This episode reveals that Ch'Rell attacked the Utrom headquarters in Japan a few decades prior to the present day. This causes a continuity error in that his confrontation with Mortu in "Secret Origins" made it clear this was the first time the pair had encountered each other in thousands of years, let alone Ch'Rell having encountered the other Utroms.

-->'''Hamato Yoshi''': [Later, to his pet rat] ...I will name you 'Splinter', to remind me of what I have done, and what I have failed to do. And together we will remind each other of Tang Shen.

* YouHaveFailedMe: Given a twist after the Utroms and Guardians escape in their pods. The Shredder is most displeased with Mashimi for this, but he doesn't kill him on the spot for this. When Yoshi storms Foot headquarters, Shredder decides that Mashimi will be only be spared if he defeats his old friend in one-on-one combat. Mashimi loses and is killed.
