Stage 1 - You Should Never Play Near Electrical Outletz
Go get the megaphone and you've gauntletz. Kill the enemy gruntz, hit the lumps and you'll find some zap cola and a toob tool. Pick up the squeak toy and proceed to the seven lumps, smash the most right one and wait there. You're other grunt picks up the toob, enters the pool and starts fighting near the zap cola with the enemy toob grunt. Then hit the black one switch on the island and get the megaphone on the next island. Swim to the green pyramids near the shovel. Give the wingz from your resourcez to the gauntletz grunt so he can fly towards the green toggle switch. The toob grunt picks up the shovel, digs up a keg of zap cola, closes one of the holes and both gruntz proceed to the checkpoint.
Lure the enemy sword grunt close to the checkpoint before you give him the squeak toy, this makes it easier to pass him later on. Hit the orange switch and both gruntz walk into the next area. The shovel gruntz kills the enemy gauntletz grunt, fortunately there's enough of zap cola. Go downstairs, both hit the purple switches to release your gauntletz grunt. He smashes the lumps in the corner and hits the green toggle switch. All three gruntz go upstairs, hit the orange switch and go downstairs to the next area. Use the shovel grunt to get to the zap cola and the brick layer tool. Give this tool to the wingz grunt. The shovel grunt and the gauntletz grunt together kill the enemy gauntletz grunt.
Go upstairs, dig up some zap cola if you want and put the gauntletz grunt on the green hold switch. The other two gruntz go downstairs. The shovel grunt walks to the right, opens a hole to get rid of a ball and steps on the red hold switch. The brick grunt passes the two red pyramids, lays a brick near the black one switch and hits it. Both gruntz walk back towards the gauntletz grunt and together they hit the checkpoint. The shovel grunt and the gauntletz grunt attack the enemy gauntletz gruntz one by one. One of your gruntz hits the timer switch, zigzags through the pyramids and steps on the red hold switch so the other gruntz can proceed. The gauntletz grunt smashes one of the bricks around the black one switch and steps back. The shovel grunt digs up a bomb and blows up the brick (and himself of course).
The gauntletz grunt smashes the next brick, hits the black one switch and both your gruntz go downstairs. The gauntletz grunt picks up the kart, smashes the three lumps and collects the coin behind the bottle. Give the kart to the enemy club grunt. The brick grunt lays a brick to get rid of the balls. The gauntletz grunt smashes it again, walks on, smashes the red brick and looses his gauntletz. Both gruntz pass the slimy area and cross the outlets. The brick grunt kills the enemy sponge grunt. The barehanded grunt goes right and passes a lot of outlets before he reaches the gauntletz. Smash all the lumps, walk down, hit the black one switch and enter the blue warp.
Now the gauntletz grunt has to go over the same outlets again to trigger the red warp.
After entering the warp just step on the arrows. This takes you near the sponge grunt. When he's ready to shoot you step on the marked arrow, wait a moment and step on it again. This will get you onto the outer arrows. Now you zigzag towards the warp letter, walk back, get the coin and enter the red warp.
After hitting the secret ? switch the wall disappears for a while, just ignore this. Have your brick grunt wait near the coins surrounded by holes. After some time the holes disappear for a moment, and a hole appears and disappears under the coins. That is the moment to get the coin, start with the upper one.
