Holy Pedestal (聖なる台座, Seinaru Daichi) is an event in Tomba! 2: The Evil Swine Return.
Place something on the pedestal to keep the holy water running in the Water Temple.
Activate the event by stepping on the pedestal in the second area of Water Temple. Go back to the sculptor you met during The Ultimate Sculpture event in Ranch Summit. He has created a sculpture out of the Eternal Ice Block and is willing to give it to Tomba.
Go back to the pedestal in Water Temple and use the newly obtained sculpture to keep it down. The event is cleared.
