Q: When a Goal asks for a Keeper and “any Creeper” or “a Creeper” are you allowed to have only one Creeper, or do Goals like this allow you to win regardless of having multiple Creepers?

A: If a Goal requires any Creeper, then it’s fine to have more than one Creeper. The idea here is that problems are needed, so extra problems are not a problem.

Examples of this would be:
