Spots on kitchen wall
Sounds like signs of a
dtradin infestation. Hide the blender.
Or, the blueberries.
FYI, putting very hot blueberries into a blender will cause purple spots on your walls, ceilings, clothes and cabinets. Typically, spots are not uniform so I suggest you lick the ones in your kitchen to see if they really are yummy blueberry flavored spots from an exploding blender.
