Yet another ZX Spectrum release from the Mojon Twins. As the Mojon Twins explain, the title - which is in Spanish - is a play on a Spanish game by Topo Soft called Viaje al Centro de la Tierra, which roughly translates to "A journey to the Centre of the Nose". This time, the player controls Miguelito, who is inside his own skull searching for twelve pencils, so that he may escape from this nightmare.
