I’m searching for an method to resolve a picket packing puzzle which my three-year-old acquired as a gift.
We enthusiastically unpacked and disassembled the puzzle when she acquired it.
Since then, we have been unable to place all of the items again collectively.
Occasionally I get it out and try to resolve it once more however fail, though it appears trivial at first.
It is irritating.

This is a polyomino puzzle with twelve items.
The smallest consists of 4 cells; the most important of 21.
The field is a sq. with twelve squares to the facet.

So far, the one progress that I made is:
The violet toucan should go into the inexperienced chameleon.
There isn’t any different approach of filling that area.

I’m unable to search out the answer on-line.
I discovered visually and conceptually very related merchandise, however none with the identical shapes.

At this level, I’d even take the answer in order that I can put all of the items again collectively.
However, I’d most recognize an evidence of tips on how to go about fixing such a puzzle.
