FINAL ANSWER:

RAVEN RIDGE

OH MY! The Ravens STOLE the Ruby Tiki!
We never said how big it was, so I guess the ravens were able to fly away with it. I guess even a ruby worth a bajillionzillion dollars would still be pretty small.

Did you know common ravens and crows are known to steal shiny objects such as pebbles, pieces of metal, and golf balls. (And I guess tiki statues?)

Research indicates that these birds are deeply curious about all new things, and that common ravens retain an attraction to bright, round objects based on their similarity to bird eggs.
