I want the trolley to be made out of metal because it is very strong and won't break in a crash.
I want wheels that will look like wooden boat steering wheels, with handles outside the circle but they will really be proper wheels, made out of metal with tyres that have air inside them because they will be fast and strong and they won't wobble.
The steering wheel will look like a steering wheel on a boat, too. But the sticky out handles must be soft and short so that I don't knock my knees on them.
I will have a seat with a harness like my car seat so that my chin or my knees won't bang in to the steering wheels if I crash.The brakes will be made out of strong plastic like on a moped but I will put them on with my feet, because my hands will be holding the steering wheel.
It will go as fast as 55 ks and when I cross the finish line I will put on the brakes water will shoot out of the little holes in the back so that it looks like a rooster tail on a jet ski at the back.
The brakes will have to stop the trolley just two or three houses after the finish line so that I don't crash into the hay bales. If I go around the hay bales I could crash into the roundabout, or I could keep going all the way down Collingwood Street, over the bridge and into the haven, where the fish won't see me because my trolley will be camouflaged.

My imagination trolley will be a blue and yellow submarine. It will look the same as my real trolley, The Heart of Gold, but it will look like it's underwater.
On the outside, it will be blue and all the different colours that are in the sea; like fish and seaweed and rocks and sand - we will draw everything that's under the sea and that's why it has to have a boat steering wheel.
I will be wearing my snorkel and goggles in blue clothes with a helmet that is the same as the deep blue sea because it's supposed to be a submarine.
There will be a button on the brakes that makes a rooster tail of water spray, like behind a jet-ski.
I really like kayaking out to the Boulder Bank and under the wharves at the port, where there are lots of starfish and mussels.
There is a famous submarine called the Yellow Submarine. I like yellow a bit because yellow is a good colour for fun and the sun and that's why the inside of my trolley will have to be be yellow.
People will see that its yellow inside because there will be round windows like on a submarine. But I want it to be blue on the sides and the on the top because light blue is my favourite colour and that's why it has to be a submarine.
I will need help from the mentors because I don't know how to make a rooster tail of water come out when I use the brakes. Maybe we could use toi-toi branches instead.
My imagination trolley design should win because it is very clever and it will look like fun.
