Favourite "Technodrome-moving" episode

[pannoni1]

The "Big" trilogy, specifically the second two episodes, since the Technodrome doesn't actually move in "The Big Rip-Off". In "the Big Break-in" itself, the two commercial breaks are among the best placed in the whole series: the first right as it encounters the Turtles not that far underground and the second right as it emerges from the ground onto the surface as it threatens to kill April. It makes you see why commercial breaks served good cliff hangers (even commercials were better back then instead of this infomercial/home shopping-style crap), it made you cry for a couple minutes that the good guys may perhaps be seeing their end. And the "Big Blow Out" is the only episode where the Technodrome is squarely a threat above ground in the city, causing all of the armed services to flee, leaving the Turtles as the only hope to save the world!

Don't forget a couple other episodes, such as one in Season 7 where the Technodrome briefly emerges from the ocean before being forced back underneath.
