"That's a Keyless Bob-omb. It's a Bob-Omb with no key. As if it wasn't obvious by the name. Max HP is 2, Attack is 2, and Defense is 1. Like other Bob-ombs, it attacks by blowing itself up. However, this one blows up upon being defeated, so make sure not to attack directly."

"That's a Blue Bob-omb. It's much more sturdier than regular Bob-ombs. Max HP is 5, Attack is 4, and Defense is 3. Just like with regular Bob-ombs, it'll get mad if you hit it and explode on the next turn. Their defense is pretty high, so you'll need to pull out your strongest moves to finish it off before it goes off!"

Something a bit simple, both variations of Bob-ombs from SMB3 integrated into TTYD. Always found it kinda weird they were purple and blue when all other games depict them as solid black.
