moves in a specific pattern. There are five species of Troggle, each of which has an English and a mock-Latin (binomial) name: Reggies (Trogglus normalus) (magenta on Apple II, red in DOS, purple on Macintosh) - simply moves in a line unless redirected by a safety square in its path. Bashfuls (Trogglus timidus) (green on Apple II, blue in DOS, pink on Macintosh) - moves in an arbitrary manner on the gameboard, unless approached by a Muncher, in which case he moves away from the Muncher. It became purple in later releases in the series. Helpers (Trogglus assistus) (green on Apple II and DOS, magenta on Macintosh) - this ant-like Troggle eats all answers, leaving nothing behind. It became purple in later releases in the series. Workers (Trogglus laborus) (purple and white on Apple II and DOS, magenta and white on Macintosh) - this Troggle adds new answers and/or changes existing answers as he moves around. Smarties (Trogglus smarticus) (green on Apple II and Macintosh, yellow on DOS) - has large teeth and glasses, and the most difficult Troggle to avoid; always follows the Muncher on the board. Safety squares occasionally appear to help protect Muncher from the Troggles. These are temporary havens identified by four small white rectangles on the corner of the square. No Troggle may enter a safety square; if one appears on a square a Troggle currently occupies, that Troggle dies (but may be replaced afterwards). Safety squares may disappear as quickly and randomly as they appear; hence, one must take caution not to remain in one for long. In addition, Troggles are quite cannibalistic; if one Troggle enters a square already occupied by another, or if two of them enter one square at the same time (even if they are of the same species), one Troggle will eat the other, although another Troggle may re-enter the board afterwards. Levels Players can choose from the five modes of play, or choose a "challenge" mode, which randomizes these modes. In the Multiples mode, Muncher must munch all numbers which are multiples of the number given; for example, if the designated number is 3 then Muncher must eat all 6's, 9's, and 12's and avoid numbers such as 7. In Factors the muncher seeks to ingest the factors of a given number, in Primes he craves prime numbers, and in the Equality and Inequality modes the muncher devours
