Review:

The Big Sister’ is the second of four pilot episodes of ‘Dexter’s Laboratory’ that appeared on Cartoon Network before the official series was launched. ‘The Big Sister’ then would reappear as the third part of the sixth episode.

This sequence starts with the zoom into Dexter’s lab that was later reused to start the end titles. In these we follow a smell that turns out to be from chocolate chip cookies made by Dexter for his laboratory rats. Of course, Dee Dee wants one, too, but the cookies contain secret formula X27, which turns Dee Dee into a giantess, rampaging the city. It’s up to Dexter to save the world!

This episode contains nice references to both King Kong and Japanese mecha films. The episode clearly borrows from the mecha anime visual style, something that would permeate the complete Dexter’s Laboratory series, blending surprisingly well with the 1950s cartoon modern style to create something new and fresh. Nevertheless, highlight of this episode is when Dexter’s fantasy runs away with him.

Watch ‘The Big Sister’ yourself and tell me what you think:

‘The Big Sister’ is available on the DVD ‘Dexter’s Laboratory Season One: All 13 Episodes’
