Catch 'Em Mode can be activated by sending the ball through the right loop twice, lighting up two Catch 'Em arrows, then sending the ball into Bellsprout's mouth. Some Pokémon will only appear when all 3 Catch 'Em arrows are lit.
EVO Mode
Sending the ball through the left loop three times will allow the player to activate EVO mode by hitting the ball into the hole previously guarded by Ditto. After choosing a Pokémon to evolve, green arrows will appear pointing to locations on the field. Hitting them places evolution items somewhere on the field, and collecting all three (within the two-minute time limit) will allow the selected Pokémon to evolve.
If the chosen Pokémon is already fully evolved, the player will instead get a 10 million point bonus upon collecting all three items.
Travel Mode
Hitting the head of Diglett three times on a single side will allow you to instigate travel mode once sending the ball through the directed loop and landing it in the hole in the field's center.
Bonus Fields
You can access the bonus fields by capturing and evolving Pokémon. The first Bonus Field focuses on Diglett and Dugtrio. The next field is a graveyard battle against Gastly, Haunter, and Gengar. The third and final stage is against Mewtwo, once defeating him you begin the cycle again.
