Lizard on Step 5.10.12

I found this lizard on the step right when I walked outside from door. It was quite a surprise. Also surprising was my math test score that I found out: a 103! and no missed questions! How awesome is that? Does anyone know what kind of lizard this is?

I think his tail is broken.

Nice composition. Is his tail broken? Congrats on the 103 test score!

I think he's a grumpy lizard..! Well done on your maths. Only time I ever got 103 was when the top score was 400. (!!)

This is a cool looking lizard!
