You might be able to right-click the clipart object and select "Grouping",
"Ungroup". You should be asked if you want to convert this to a Microsoft
graphic object. Clicking YES will allow you to click "Grouping", "Ungroup"
again, ungrouping your clipart image. There you can select and delete any
part of it you want, changing colors of others, etc. When done, draw a
selection around the remaining stuff and right-click, select "Grouping",
"Group" and you have one object again.
Hope this helps!
