Hurricane pattern
the hurricane pattern refers to the dark or light coloring immediately surrounding the dots on the motley pattern. You do not need a perfect dot dot dot pattern to be a hurricane pattern, you just need the surrounding color that immediately circles the dot and looks like a miniature hurricane. You can have a hurricane pattern with a mostly striped/mot pattern, too.
The hurricane pattern is hard to see on Walters caramel motley, but it is the subtle, black coloring immediately around the light dots. It is easier to see on Walters butter motley and it is easy to see on the adult butter motley from Old School, kind of an orange color surrounding the yellow dots, and also easy to see on the anery mot of Ravenspirit, the darker coloring surrounding the light dots. So, with hurricane you have the dot, then you have the color around the dot that highlights it, then the base background color. You do not see a hurricane pattern on the other adult butter motley pictured from Old School, even though it has a perfect motley pattern, hope that makes sense,
