Spongebob Atlantis Squarepantis game for Nintendo ds. Where are the red and blue jewels?

I need to find the red jewel by the volcano and the blue jewel in coral cave. I've tried everything. I'm helping my son's and we can not find them.Spongebob Atlantis Squarepantis game for Nintendo ds. Where are the red and blue jewels?
Im stuck aswell!

Go the coral cave, which is the blue cave, and travel through until u reach the blue gem, then when ur back out, go to the volcano cave (the reddish one)

then once you have both of the jewels, go to the blue pillar looking thing, and then u insert the two jewels in the door.



Im stuck on having to get into the volcano cave, but i hope you find your way, and help ur sons!



Hope i helped and best of luck! :)

You go to the kings bedroom and there will be a little string by his bed and when you walk on it you will see them all over.
