The player has to drive a funny grub on the surface of various vegetables and fruit, trying to eat all the parasites, while preventing it from colliding against his own body and against an ugly and bad grub.
Every time our grub eats a parasite, his body grows longer of a given length, thus making the game harder. Fruit and vegetables can have holes, to be used as tunnels. Various bonuses and power-ups are scattered around:
- scissors, that shorten the grub's body of a certain lenght;
- shield, that makes the grub unbreakable;
- extra life. 
When two or more parasites are eaten within a short time interval (represented by a bar on the top of the screen), the earned score increases more than proportionally.
Two playing modes are provided: Trial, in which the player can practise, and Career.
High scores achieved in Career mode alone can be stored. As the player goes on in Career mode, he unlocks new levels for the Trial mode.
