Thunder - How Did That Happen?

I can see what is on the chair.

I was shorter than the hassock.

Now I am stuck between the couch and the hassock and can see over it.

I was shorter than Justice.

I weighted 5 lbs and was 9 inches tall.

I am still shorter but I'm getting taller.

I weigh 35.4 lbs and I'm 20 inches tall.

How did that happen?
