Sam and Max Hit The Road Easter Egg - Purple Tentacle & Guybrush Appear During Credits

You will need to complete the game to see this. During the end credits, you will be able to see the silhouettes of carnival toys (or targets) moving along the front of the screen. The order in which these toys appear on the screen is completely random, so just keep your eyes peeled.

There is one target in the shape of a man with pirate clothes, long hair and skulls on pins sticking out of his head. This is Guybrush Threepwood - the hero of LucasArts' Monkey Island series - or more specifically, the Guybrush voodoo doll (as seen on the Monkey Island 2 box cover) with skull-shaped pins stuck into his head. Also, there is another target in the form of a triangular character with arms. This is Purple Tentacle - the villain from LucasArts' Day Of The Tentacle.
