What is going on here Iguana?

MM reader Mike has a perfectly reasonable request:

maybe you can help solve the mystery of why someone would place an iguana in a straw basket up my tree. @ 17th and albion

I usually never write this, but WTF???  Some bizarre feeding ritual?  Fresh air?  Owner has been playing too much Skyrim and wanted to see if his reptile could fly too?

Someone better have a good explanation for this or Vegansaurus is gonna rage!
