You need to Unpin first, or Set position is ignored.

Made a few small improvements:

You don't need to move the Blaze, as it's pinned to the Rocket, so will move with it. The animation can be done by altering it's properties. Your inverted Up arrow can't work in a sub-event. (Not sure what you wanted, so just disabled it).
