Hi kids! Today, I prepared a fun little character in vector—Cactus. This will be an easy tutorial, especially for those who already know Adobe Illustrator and vector. Let me tell you, you're a very cool kid, if you know this already. We will use basic shapes, the Line Segment Tool and a Warp Effect to create a cute cartoon character.
1. Create the Flower Pot
Step 1
To create a New Document in your Adobe Illustrator, go to File > New and enter the following options:

Step 2
On the Tools panel, you can find the Rectangle Tool (M), which you will use to create the flower pot.

Step 3
Take the Rectangle Tool (M), and on the middle of your art board, draw a rectangle similar to this one:

Step 4
Then delete the stroke color and set the fill color which you see in the second image below.

Here you can see where to set the color (Window > Color):

Changing the rectangle will make it look like this:

Step 5
While keeping it selected, go to Effect > Warp > Arc. In the new dialogue window, adjust the options as you see in the image below:

Step 6
Draw one more rectangle pretty close to this one:

Step 7
While keeping it selected, go to Effect > Warp > Arc. In the new dialogue window, adjust the options:

Step 8
Combine the two warped rectangles together. Just grab one rectangle and move to another while holding the left mouse button.

2. Create the Cactus Shape
Step 1
Using the Ellipse Tool (L), draw an ellipse.

Step 2
Now, go to Effect > Warp > Arc and in the new window, adjust the options as you see in the image below:

Step 3
Take your cactus shape and place it in the flower pot. For this press Control-X, Control-B.

3. Create the Eyes
Step 1
We're going to use the Ellipse Tool (L) again to draw an ellipse.

Step 2
Add a small white circle. That's the eye.

Step 3
Create another copy of the eye by copying and pasting (Control-C, Control-V).

Step 4
Now, let's position the eyes where they belong.

4. Create the Mouth
Step 1
Create a black ellipse.

Step 2
Go to Effect > Warp > Arc and adjust the options:

Step 3
Place the mouth between the eyes.

5. Draw the Prickles
Step 1
Delete the fill color and set the stroke color.

Step 2
On the Stroke panel, adjust the settings:

Step 3
Using the Line Segment Tool (/), draw in the prickles.

6. Create the Flowers
Step 1
Take the Polygon Tool and click on your workspace. A new dialogue window will ask you how many sides and what radius you want. Make 6 Sides, and for the Radius, it doesn't really matter—just not too big. Once you're done, press OK.

Step 2
Delete the stroke color and set the fill color, which you see in the image below:

Step 3
To make the flower from it, go to Effect > Distort & Transform > Pucker & Bloat.

Step 4
Using the Ellipse Tool (L) add a yellow circle in the middle of the flower.

Step 5
Make another copy of this flower (Control-C, Control-V) and place it on the cactus.

7. Create the Background
Step 1
Using the Rectangle Tool (M), create a square that is 600 px in width and height.

Step 2
Place this square behind everything (Control-X, Control-B). Voila! That's it!
