Here are the N. Sanity Island Gems; Red Gem - Chase the chickens out of the coop. Run them
into the Nitro Crates until you hit the one with Bounce Crates on top of it. Blue Gem -
Hit the bomb switch until all the totem gods don't have spikes on them. Yellow Gem - The
final one. Jump on the Crates carefully until you hit the T.N.T. Crates. A Steel Crate
will fall down into the Nitro Crates. Then, grab the gem. Purple Gem - In the second part
of N. Sanity Island, chase the chickens into the Nitro Crates. A Bounce Crate will fall
down. Then, you'll be able to grab it, like the Red Gem. Green Gem - Same as Purple and
Red, but instead, you don't chase the chickens. Clear Gem - Use the board to slide onto
another island. Jump on the worms to get it.
