The Z3d stands for zebras in 3d which references an hallucinative pill. These kind of drugs are very heavy and are usually given to children giving them wild fantasies. Its not uncommon for exposed children to make up fake friends whom does not exist!

The hit movie Stuart Little was created with directors taking the hallucinative and making shit up. Stuart little is a matte of fact not real but made up! However your perception of reality can only be based your own interpretation of the world and thus taking this pill can recreate your love for Stuart little and therefor Stuart little will once again be real so you can be lovers for eternity.

I really miss Stuart, no homo though.
