The official description names the Clock King as the boss to take down. A Roblox badge, Beat the Clock King!, tracks that victory. The badge text does not add a difficulty or a required world list.
Where the videos place him

The castle video's description calls him the final boss and calls the world The Clock King's Castle. That is the uploader's structure. It supports watching the fight there. It does not prove that every earlier chapter is a prerequisite, or that solo and co-op use different ending rules.
The throne room
At about 48:53 in the full run, the king has a clock face, a gold crown, and a purple robe. He sits on a throne with a scepter. Gears and a giant clock fill the room. Two players stand on the left in that frame, and the weapon label reads SPLITTER. Attack patterns, phase count, and a recommended loadout are not in the checked frames.
The ending frame
At about 53:09, the ending chapter shows a bright hub with shop stalls, string lights, trees, and benches. Signs read WARDROBE, SALT TAFFY, and PASS. A SKIP button is on screen. The frame does not show dialogue, credits, or a reward list. SKIP does not, by itself, explain what can be skipped. No alternate ending is documented.
If you want the fight without that hub, stop before the ending timestamp.
What is still open
The sources do not say whether Expert is required, whether the badge needs Regular, or whether the clear pays Ink, a cosmetic, or a boss skip. The like-goal reward on the game page, a Boss Skip and 100 Ink at 10,000 likes, is a separate announcement. It is not the ending reward, and it is not a code.
