LEGO Star Wars 3: The Clone Wars Minikits Guide

Geonosis

Destroy the five carts located around the area's perimeter. You'll receive the first Minikit after destroying the fifth.

Take a small character (Yoda or Wag Too) and head to the north wall of the arena. There'll be a small hole for you to climb through and you'll find the second Minikit on the other side.

Use the Force to build up the pieces of the pillar in the center arena by placing them on the purple panel. Make sure to give yourself some climbing room by building the pieces unevenly (not perfectly on top of each other). Use Jar Jar to climb to the top and a double jump of his will collect the third Minikit.

To the left of that panel, you'll find another pillar. Use a Sith's Dark Side to open up the contraptions attached to the pillar. You should then be able to grapple both hooks and the pillar will collapse. Minikit #4 will be your reward.

Head to the west side of the arena and you'll find a closed gate that needs bounty hunter clearance. Use Cad Bane or Aurra Sing to open the door and make your way inside. You'll find yourself in a nice Geonosian exercise room. To obtain Minikit #5, run on each of the three treadmills until they explode.

Before you exit, switch to a rapid fire character like Lieutenant Thire with his minigun. Fire away at the gold-plated object on the west wall. When you destroy it, you'll notice you have four more to destroy. The remaining four can be found around the perimeter of the arena. After glassing them all, you'll be the proud owner of the sixth Minikit.

Switch over to Robonino and activate the console on the east wall of the arena. This will bring up an electric fence and you'll automatically corral one Destroyer Droid in there. To collect the seventh Minikit, head to the center of the arena to find the rest of the Destroyer Droids. As a Jedi (or Sith), Force-push four of them in that electrical area.

In the northeast part of the arena, there'll be some loose gold pieces on the ground. Use them to build a familiar droid and Minikit #8 will be yours.

Around the perimeter of the arena you'll notice some small sandboxes. It's time to do your part to save the environment by planting some flowers. In order to do this, you need to pick a Jedi first. Double jump and Jedi Slam onto the sand, which will somehow get the plant to sprout. Then, you'll need to switch to a Sith and place the flower in the pot next to the sandbox. Do this for all five sandboxes around the arena to collect Minikit #9.

The last Minikit can be found by putting your sniping skills to the test. Choose a sniper like Aurra Sing and head to the south wall of the arena. Then, hold your Attack Button to pull out your scope. 10 ducks are hidden around the top of the arena, so shoot them all before that blasted dog comes to laugh at you.
