Looking at some art, I began to notice that England has a cow companion.
In the art pictured, a young England seems to be playing with a cow as well as a fairy. Perhaps this is because in British folklore, Fairies enjoy milk, hence England enjoying cows.
The cow is also in the "He Loves Fishing in Troubled Waters" strip. It is pictured alongside England, sticking its tongue out at Spain.
If anyone has more information about his cow, I'd be happy to know! I just thought it was intresting.
