My favorites were the otters, turtles and the amazing walk-though tunnel with sharks and one big turtle! The mirror labyrinth at the end was pretty fun too. As the pussy I am I had to walk thought that with one hand stretched out. No way that I was going to crash into some mirror with people around!
And another favorite part was walking around with M in the souvenir shop at the very end, where I fell for a cute turtle teddy and M bought me it.
