To approve or not to approve? That is certainly not the question.
In order for a user to interact with Blobble game play, certain permissions must be given to the Blobble contracts. For example, unhealthy Blobbles must be moved to the Orphanage. This would not be possible without essential permissions.
Here's two facts about signing off on Blobbles necessary contract permissions:
Upon Blobble minting, a user automatically signs off on the necessary contract permissions for Blobble game play to be enabled.
When a user does not mint a fresh Blobble, but decides to stalk the Orphanage instead, this signing off on the necessary contract permissions must happen manually.
