Doktor Proktor a konec svta. Mon… – CDmp3 (te David Novotn)

In this Czech-language third adventure featuring the eccentric inventor Doctor Proctor, diacritics begin disappearing, followed by socks and eventually peoples own opinions, suggesting an alien invasion. Doctor Proctor, Bulle and Lisa form a revolutionary resistance group, joined by Mrs Strobe and other distinctive members of the teaching staff. As the Five Unvanquishables, with indispensable help from Perry the Peruvian absorbent spider, they fight extraterrestrial chameleons who want to eat humanity for breakfast, lunch and dinner. The humorous story is performed by David Novotn.
