Here is the full video of Konstantin XI (Kostyan) Demonstration in Advanced Education with Viktor Strobovski.
Konstantin XI, also known as (Kostyan for short), is a character in the Language Level after you beat the Math Level. Konstantin XI is a replacement of The Puppet. He starts between the two pillars in the hallway to the garden.
When not active, he will play the music "Dance of the Sugar Plum Fairies". After being in Konstantin's line of "sight" once, he will activate.
He won't start moving until the music stops. He behaves very similar to SCP-173 from the SCP - Containment Breach Game and Specimen 6 from Spooky's Jumpscare Mansion and Spooky's Jumpscare Mansion HD Renovation, where you have to look at him and he won't be able to move. However, if you look at him, he will drain your sanity. But the longer you look at Konstantin XI, the more and faster sanity you'll lose.
If you don't look at him and he's close enough to you, he will bite you, making you lose blood. If he bites you too many times, he will kill you. The total bites he will take to kill you is he will bite you 6 times.
Cleany likes to sweep Konstantin XI around, A LOT. So be very careful of Cleany, cause he can sweep anyone anywhere he goes.
