The Cave CGI
 

Was it really necessary? Sure, when Dex used his crystal the first time to bring Combat Chopper and Magno to life it made sense, but for them to go through that whole labored transformation episode after episode was grating. And the only reason they transformed from bugs was I assume due to them hiding in organic forms in case a stranger stumbled into the cave.

Yeah after a while of seeing that, it gets pretty annoying doesnt it?

Saban liked to use stock footage to fill time. I remember how they put the transforming clip to every episode of Teknoman to make episodes a bit longer, after they cut RAW source.
