Wow! I love this poem.
I love how you rhyme but it's not in an organized scheme. It's hard to pull off, but you did it wonderfully and it flows very nicely.
You have a very good vocabulary yet you don't overuse words to sound smarter. You use just the right amount to make your point and to be descriptive.
I love how you come around at the end and bring in the toy who's a boy. You should fix the 2nd line, by the way. It should be "who's," not "whose."
There are a few minor mistakes, such as not having an apostrophe between the "t" and the "s" in "Lets." Unless you purposefully left out commas and periods, I would suggest adding them.

I LOVE this line. The constant rhyme with brain and lain and came (though came is a slant rhyme since "m" is used instead of "n") sounds wonderful and it really adds a rhythm to the poem and it flows great.
You should add this poem to the writing arena if you haven't already; I don't know if you're interesting in doing so or not, but it's just an idea. :3
