Consuming Blob

The above rulings are also true for Consuming Blob's children (except the first one, as Junior tends to not hang out in graveyards).

If an instant or sorcery spell deals damage to Consuming Blob or reduces its toughness to 0, that spell is put into its owner's graveyard before state-based actions are performed. If that card is the first of its type to enter the graveyard of Consuming Blob's controller, it will raise Consuming Blob's toughness before the game checks to see if it dies.

The ability that defines Consuming Blob's power and toughness works in all zones, not just the battlefield. If Consuming Blob is in your graveyard, it will count itself.
