You'll need multiple sprites for this.
Basically the most obvious way (to me) to create said enemy sprites would be to first have this after loading the enemy image:
for a = 0 to (however many you need minus 1)
sprite 100+a,(X),(Y),(image number)
next a
(X) and (Y) should be replaced with the intended X and Y coords (try hiding them off screen) and (image number) is just the number of a loaded image. You can have any sprite number but I only used 100 onwards as an example. Basically to tidy things up. I like to separate groups of sprites to avoid confusion if I leave a project for a while.
To make them actually appear on screen:
for a = 0 to (however many you need minus 1)
sprite 100+a,(X),(Y),(image number)
next a
does the job.
See how far you get with this for now and just say if you need more help. I'll be able to help further on this post, but I'd probably end up feeding you too much info at a time.
