I know its planet coaster, but there are many coaster parks with water slides I.e. Kings Island. Some water slide track pieces I think would be cool include1) open (U shaped cross section)2) closed (O shaped cross section)3) pieces LED lights4) pieces transparent walls5) end pool/end stop6) wider track pieces, open and closed, for single or double tubesSorry if I overlooked someone else mentioning this. Let me know what you think , also watch video below !
