I'm stuck on the blue statue. I have the diamond and ruby. What else am I looking for?

Have you looked carefully for something new in the vicinity of the statue?

I had a chief. I finished the yellow statue but something is not trigging for me. I dropped the chief several times on the plans but she wonders off to do something else.

Nevermind. Got a new chief and she worked it out.

Is there away to trigger the red statue event or is it a waiting game?

Do i need a chief in order for the box for the red statue to show up?

BORED!! I finished all my puzzles but the red statue.

I dunno, since there apparently is a part II, I'm collecting and crafting in case we need any of that stuff. Also, doing my best to fill my bank account since I don't expect tech levels to be cheap. The peeps have other actions which are fun to watch. I never tire of the cliff divers, for instance. Finally, I'm on the watch for things that will help me solve a couple of puzzles I have left to do. If all else fails, I watch ads to earn lavastones. There are a couple of interactive ones that are fun, although briefly and repetitively.

I don't see any statues. Are they supposed to be visible? I used the purple necklace and a yellow statue emerged from the ground, only to disappear again.

That sounds like a bug. You should report that to them to get help with it. There's a Help button in the options menu. Just tap the gear to get to it.
