Ready 2 Rumble Boxing: Round 2 Get a red or gold "Rumble" and your opponent down to around one quarter power or less. Use the Rumble and the flurry (X + Y). It should leave them punch drunk, with no life. If timed correctly, you can use the flurry again while they are punch drunk and the rumble will wear off in the middle of the flurry. This will cause the rumble to begin to add up again, and since your flurry will keep them standing, it should allow for at least the first level of rumble if not a few red letters.
