When in doubt, trampoline.
On a side note, has anyone been messing with the thing I don't think has a name where you do -> <- really fast to cancel the initial frames of a dash into a dash in the other direction? When you do a grab or DA out of this you get an extra boost. I know Ally uses it a ton to get grabs on Mario.
Been a while since I posted, but here's stuff I found with that recently:
When combined with Hydrant water this gives us a LARGE momentum boost on our grabs and DA. Grabs cover like half the stage instantaneously, and the DA this is situationally useful by itself, but a lot more valuable when mixed with ledges and traps. When you do the DA boost near the ledge, then have the water push you off the ledge, you retain the momentum boost but go back to neutral. This is really good for chasing offstage while making it seem like you just messed up.
Also PepeSpain's Pacman video that was frontpaged had a thing where he ran off the hydrant and immediately Z-dropped a melon (

If you instead throw the melon in front of you this is a good way to follow it as well.
EDIT:
Yoooo...
When you do that boosted DA and have the water push you off the ledge, the 1st and second hit of DA will combo into an instant Nair. Near the ledge that can be a great way to close out a stock.
