Frog Gutter Guardian Downspout Statue

I have used these frog downspouts for years. I really like them. They are attractive and whimsical. I recently ordered two new ones and found that they have been redesigned to have a quite a bit larger rear opening than the previous 2.5 x 3 inches. This makes them usable on a wider range of downspout.

I saw this frog gutter downspout at a home in Texas and couldn't want to order them for my home in Florida. I'm also having trouble finding a downspout extension to fit into the hole in the back of the frog. It just won't fit inside snugly and won't stay put. They're very cute anyway just sitting in your flower beds but not too practical for the downspout purpose.
