This episode represents a significant step above its predecessor, Gamera Vs. Gaos, and the point where the film series on this show starts to get REALLY good.
One thing that definitely helps is that the humans are more likeable this time around (or are at least more tolerable this time) than the opal thieves from Barugon. You’ve got that goofy comedic duo emerging from the real estate development subplot, prompting Crow to menacingly intone that they’re “sending over a couple of blood donors” for the bloodthirsty Gaos.
Yeah, the kaiju certainly provoke some of the most inspired hilarity, but not all of it, as Joel proves in reaction to the farmland sounds of one particular scene: “Would someone please milk Grandpa, he’s in a lot of pain!”
We can’t forget about Itchy, the kid who forms a bond with Gamera, because they throw some great riffs in his direction. Among them:
Crow as Itchy: “I’m only six! Who do you think I am, Carl Sagan?!”
Servo as Itchy: “I don’t know where my friend went, but there’s a pile of poop here with shoes in it!”
Joel: “I like how suddenly the kid’s in authority.”
Joel as Itchy: “Mom, if the UN calls, I’m playing with my slot cars.”
That, and West Side Story “Boy, boy, crazy boy!” riffs kill me every damn time.
THE KAIJU STUFF 
What makes this episode cook is the movie ramping up the goofiness. Here, it’s all in the elaborate and bizarre plans to kill Gaos (which made enough of an impression on the writing room to inspire viewers to write in with ways to snuff Gaos).
I mean, trying entice Gaos with the blood fountain thing… what the hell?
Servo summarizes the strangeness of it all so flawlessly and humorously with: “This is so goofy. Operation Goofy in full effect!” And you have Crow chiming in with choice riffs like “Okay, let’s face it, he likes blood, but not the way YOU make it” and “nothing like Bloody Mary in the morning.” Joel lands decisive blows like “All right, it’s the last resort, send up the peel-and-eat humans!”
And I’m always a sucker for a “Do you want to go faster?” riff in response to the onscreen absurdity of trying to spin Gaos to his death.
Naturally, the headline fight has great hilarity to offer as well, such as Crow likening the clash to a hockey game: “Cross-check! He’ll be in the box for two!”
Gamera Vs. Zigra and ESPECIALLY Gamera Vs. Guiron would improve on what we see here (in terms of both the film and the episode), but this is a damn fine episode in its own right, and well worth repeat viewings.
