I want to only spawn the pump and not the pipe with a cork in it.

What sprite data / sprite id / class id / way
is there to make only the pump appear?

Don't think it's possible
Maybe you can place it at the edge of the screen so the pipe is out of screen

Anyways, what would be the use of having the pump alone? It's just a pump, you can't activate nothing with it (?)

I cannot place it at the edge of the screen because I them spread out all over the level

I was not going to activate anything with it.
I was going to use it as a platform like the Yoshi's Island ones:

But later I realised that you would not be able to tell whether it will disappear immediately when you step on it or whether you can step on it a few more times.

Could this be a hack in the community remix? (a hack to make only the pump appear and to make the graphics change each time you step on it)
