Here is the solution of the riddle
A very colourful beast
I'll show you the steps how it came to this.
After the first "mousy" bit, I attached the tail and a crest,
and the tricky bit : the legs
Because the feet were a bit too big, I just cut some bits off.
(this doesn't matter because I had to add another layer of wool)
Just like a real chameleon
he slowly changed colour !
till he was ready to dry
(Mmmmm ... silly beast, thought Bella)
Daughter continued too with a new project
after we took some new pictures of the (now dry) hat
This will be a jacket
