If it is a relatively young guinea pig, it is probably the remains of the umbilical cord. When baby guinea pigs are born, the mothers chew through the umbilical cords and sometimes a small portion of the cord remains. It usually dries up and falls off, but there will always be a little bump (sort of like a human belly button) where the cord used to be.
Um, I'm fairly positive that hole you saw was his belly button, and yes it is very normal in fact all guinea pigs have them.
As big as your belly button.
No
In that case, it will stay there.
A hole
yes. just soak it with a saline solution to remove it. DON'T pick at the scab.
Your belly button does not close. You are stuck with it for life.
It originally was the umbilical cord, which was cut and tied after birth.
It does appear, but not as a hole. The tissue usually flops over.

you get the glowstick and then go in the sewer hole........ you go where th blood writing is and then there will be somthing there........
