Where are the Pokemon with the three secret words on Pokepark?

porygon z (granite zone), togekiss (granite zone), snorlax (cavern zone).

I have been to these Pokemon and none of them give me anything, what do i need to do. i am completely stuck and can't get any further.

When you talk to the Pokemon you do a skill game (Porygon is a quiz, Togekiss is obstacle hop and Snorlax just gives it to you) and then they give you the secret Word.
