The clone wars shorts are good, but they are not accurate in the events they portray as they are supposed to be an in-universe production made by that kid on Dantooine who gives Mace Windu the water bottle hence the over the top force action etc. Grievous did get his wheeze after Windu got him, but it was months earlier, its a similar issue with Anakin and his scar and it shows K'kruhk as being dead when he survived and is still alive 100 years later.
