Pinot and Lokie are showing off the fact that doxies must match the newly painted wall of your house. This is accomplished by getting a zoomie just after the wall is finished, but still not quite dry yet. Then ramming your sibling into the newly painted wall until you reach the desired painted dachshund style. Once complete your wall and doxie will match each other (until the humans give the doxies baths).
