Isabella
Holly respects Isabella, calling her ma'am or sir. However, she is very jealous of Isabella's leadership role and usually calls her just Isabella.

Katie
Katie is Holly's mortal enemy. They will do anything to make each other angry and fight a lot, though will cooperate if required.

Ginger
Ginger is pretty much Holly's only friend. They interact occasionally, which makes Katie angry.

Ferb
Holly helps Ferb a lot, though she doesn't really like him.
