The plot of the show is fairly simple. A family of two has become three. The two twins have fears that their new brother is in fact the head of an alien invasion of 'sprogs'. The animation is not my favourite style, but i wont demerit t on that account. The plots are generally simple, as you would expect, and generally most humour is simple. The characters all have peculiar quirks and individual variables, and relate to one another making use of these. One highlight is the songs which invariably appear in all episodes since the first, which are quite enjoyable. The show is quite entertaining, and could have another series, but would need to prevent tiring with fresh new plots. It seems to be quite popular and isn't that bad a watch. After all, anything beats Deal or No DEal.
