River terrapin...

I kinda sad when i check on the adoption list in the aquaria site.. I get a RIVER TERRAPIN! >_< I wanted a turtle not a terrapin..
I felt that I was being cheated... When I was at the adoption counter, the lady didn't mention much bout terrapins n it was adopt a turtle campaign! She did mention that we can't choose on which creature to adopt .. I'm fine with that ... by why didn't she stress on terrapins..?? When u check the list almost 50% of the adopters gets a river terappin.. >_< WTF la.. then the next time they shouldn't call this campaign "ADOPT A TURTLE" & it should be " ADOPT A TURTLE/RIVER TERRAPIN"
