Metamorphosis - Mr. Green transforms over my swim class

I went for swim at 6.30pm, and got home at 10pm to find that Mr. Green (aka mas green selamat) had totally transformed into pupa mode... it had inverted itself completely.. I wish I had a time lasp camera. Amazing.. sorry but i'll be a little obsessed about this for a couple more days till he stabalises. Science freak here. (:
