when is Pete skip

I'm offering a 50$ bounty if someone can find a new warp on the SNES version. Conditions: It has to be recreatable, save time in a run, and has to be in a new spot, not an improvement of another warp. The bounty is up for one new warp, no multiples.

Some guesses where new warps might be found:

• at the beginning of Wharf: some combination of the bridge reappearing, wrecking balls both on screen and getting hit, throwing marbles, collecting items
• Steps: jumping on and/or hitting butterflies with marbles while getting hit
• Library: some combination of getting hit, throwing marbles at enemies and collecting marbles
