I did this in Adobe Illustrator. I used the inflate tool to give it that 3D effect.
First you color in the emoji in Adobe Illustrator. Then go to "Effect". Click "3D and Materials". The click "Inflate". It will then inflate your emoji. When it inflates it will give you a panel for you to edit the intensity of the inflation and shine. Feel free to edit as much as you want until you like it.

I used Adobe After Effects to make this GIF. I animated the tail, the heads, the necks, and the feet using keyframing.
This is my Monster withought the animation
First I used Adobe Photoshop to edit the original draft. Then I used Adobe Illustrator to add color to the monster. Since it has so many tiny details, it was hard to color with.
