Overall, not too shabby an episode! Certainly among the best this season, though personally that's not saying much. Chompy is adorable though I find a little unnecessary. Otherwise, decent plot, characterization (about time for Raph being a perfect blend!), and sets up the next episode.
Two main issues though, the animation like
The Moons of Thalos 3 doesn't feel spectacular. As I mentioned there, the animation didn't feel entirely executed to it's fullest potential, just the generic red and black. Also, compared to
The Cosmic Ocean this episode and
Moons felt a little lackluster without enough colors.
Besides that, why was Dregg even here? I understand because of the alliance with the Triceratons, but he almost felt unnecessary to everything. When last episode left a lot of questions unanswered and then nothing to specify on it, Dregg feels like a waste. Heck, he's been a waste of a villain since the beginning with a pitiful motive and just not doing too well. His whining in the beginning just sums up my feelings of Dregg in this series: a once promising addition reduced to nothing but a spoiled brat. If he doesn't return, my analogy of him being like a child is right.
Other than pacing, nothing really to complain about. I'll give it a 6.5 out of 10.
