Roll a 10-sided die 1 time to encounter a Pokemon. The result will be the Pokemon you'll encounter:

If you roll a 1 *Dugtrio*
If you roll a 2 *Persian*
If you roll a 3 *Primeape*
If you roll a 4 *Machoke*
If you roll a 5 *Graveler*
If you roll a 6 *Muk*
If you roll a 7 *Onix*
If you roll a 8 *Cubone*
If you roll a 9 *Weezing*
If you roll a 10 *Golbat*

Generate a random number from 30-50 to determine the level of the Pokemon.

Roll two more 20-sided dice to capture. If the result is above 30, the Pokemon flee.
