Fast and furry ops level problem (solved)

[toonben]

def petMove():
    pet.moveXY(50, 21)

# Use pet.on("spawn", petMove) instead of petMove().
# This way your hero and pet will run at the same time.
petMove() # ∆ Replace this with pet.on("spawn", petMove)

pet.on("spawn", petMove)
hero.moveXY(50, 12)

I tries some other ways, the result hero and pet also cannot reached finish line together.
Can someone give some hints and advises.
Thank

petMove() # ∆ Replace this with pet.on("spawn", petMove)
