Yep
That's fungus on your Cherryhead.
Get yourself some athletes foot cream (any brand) and smear some on those areas. Repeat every day or two for a week. It'll go away.
( I usually only treat once or twice and forget about it)
One treatment usually ends it. A week will 100% do it
Anyone who keeps Redfoot should have some ATHLETES FOOT CREAM handy.
The stuff at the DOLLAR STORE is what I use. And ive been using it successfully for a long time.
