[UPDATE I: Speeds have been altered to fit the game... Those of you who thought it was too slow were right. I checked Bowser's frame rate in the game and it was faster than I had originally thought...]
Remember how I said the next Larry anim would be some tennis racket / walking poses? ...
I lied.
Instead, here's something interesting from an older game. In Super Mario World, both Larry and Iggy had this attack. They'd pull their heads into their shells and push out a fireball. Since both Mario Bros. are targets in BIS, Larry would pull out several in sequence, which the Bros. would need to jump over. (This animation is basically an example of how the attack could look. It's possible that more than one could be thrown at once or maybe he doesn't dig around in his shell for so long, but that's really up to the animator in the end.)
Also, thank for suggesting that I add the fireballs to the animation. Originally I was going to be lazy and have it just be Larry throwing nothing.
