If you think paper cuts are annoying try cutting yourself on a plastic blister pack, the packaging is more dangerous than most toys.
The toy comes in a plastic "test tube" about the size of an ordinary slim-jim drinking glass, more like a sample jar you might see in a natural history museum than the what you might think of as a test tube. The container has a small opening at the top to allow liquids to be poured in or drained out. At first all you can see is the protective foam egg which you must rinse away to reveal the little plastic alien. Mine is apparently an evil alien by the name of Shako. Inside the alien head a little light emitting diodes flashed on and off inside his hard plastic head to show it is alive, and the colours change between orange, green, or red, depending on his state of health. The body appears to be some kind of compacted foam material and the water is supposed to gradually cause it to expand or "grow". There is a feeding solution which smelled of acetone, which I'm guessing forms a week acid to create a crude battery and help power the toy. I suppose the solution might also help dissolve the body of the creature and help it grow.
The average lifespan of this creature is supposed to be a fortnight but much shorter than that if neglected. Should I write again on the subject the title will most likely be be the obituary of Shako, or probably an "Alien Autopsy".
These seem like perfect toys for Buddhists parents reluctant to give real live pets to children.
The difference between men and boys is the price of their toys.
