Okabu

• After you get the chicklet(s) across the river on the lily pads, send them down to the bushes guarding an egg in plain sight.
• After you open the gate with the bull, shake the first tree and shoot a medicine ball at the statue above the water with the lily pads and use the harpoon to get the egg down.
• When you reach the third botanist sleeping behind the bushes, shoot a fire ball at the statues next to him and one will reveal an egg to grab.

Kat Amond the Mutants

• After meeting Kat and going through the gate, there is an egg up on some cinder blocks in front of the waterfall. Harpoon it from the higher ground to pick it up.
• In the next area, there's a big statue right in front of you as you enter. However, you need to go talk to the villager all the way to the left that will complain about the pollution. After talking to him, the winds will die and you can use Kat to fetch fire balls from the tree, then shoot one at the statue to reveal an egg.
• In the area to the left with the toxic barrels in the water, use the cannon at the right (on the hill) to break the large statue and reveal an egg.

• From the start, head right and then left into the water. There is an egg in the middle waterfall.
• Once you reach the village with polluting barrels, there is an egg under the bridge just above the barrels. Recycle the barrels and then dive under the bridge to get the egg (you have to recycle the barrels first or it won't let you dive because the water is polluted).
• Up above the river in the same village, there are two bushes (off to the left) guarding an egg. Use a lily pad to transfer a chicklet over to the bushes and then grab the egg. Note that there are some rocks separating the river into two sides, so you need to get the chicklet onto the lily pad on the left side, which is near the bushes.

• When you pass the rock bridge, you'll see a large statue. Once you get your first robot that Roki can control, head back and destroy the statue to reveal an egg inside.
• When you get to the area with the Spiderbot, break both of the large white walls at the top and the right one will have an egg to pick up.
• When you get to the area with the large green boxes (one in the top right corner and one in the bottom left corner), head to the box in the lower left and head to the left. Use Kat to push the egg out under the steel beams to grab it. I was having trouble getting the egg to go the direction I wanted, but I found out if you move too far away from Kat, Kat will glitch over the beams and you can just use her to pick it up and it will let you back out from behind the beams.

• Once you're up the elevator, use the two villagers on the wall with the red "X" to the left (there are only two) and an egg will appear behind it.
• In the next area with the two mutated chicklets behind bars, the cage all the way to the right has an egg in plain view. Use Kat and the bull to open up the cage and grab it.
• In the same area, head into the water and all the way up to the water wheel to find the egg at its base. Dive into the water to pick it up.
