Glitz Pit Strategy Contest - Hallway Bowser (#17)

Hallway Bowser
Stats: 5HP/5FP/18BP (Level 5)
Badges: Power Smash, Flower Saver, P-Up D-Down, All or Nothing, Mega Rush, Last Stand, Power Rush, Fire Shield
Items: Super Soda
T1: Power Smash (39), Water Block
T2: Squirt (33), Super Soda
T3: Star Beam, Belly Flop (29)
T4: Jump (7), Tidal Wave (0)
8-input Tidal Wave. (Bring a Life Shroom, just in case - Mario and Sushie can clean up if you miss)
I wanted to use all four of Mario's moves (Jump, Hammer, Item, and Star Power) plus all four of Sushie's moves.
My other strat idea was a very similar strat to last time, a 2-turn S.J. Charge+Power Bounce, but with slight differences than Jr. Troopa. I hope this performs similarly to how that strat would have.
I wanted to make Tidal Wave "necessary" (i.e. not less than a Squirt/Belly Flop) without being very high (10+ inputs) to go with the theme while also being practical.
Remember to use that Twitch Prime sub, Kappy Kountry!
