The Titans are mentioned in LittleBigPlanet 3. Swoop had to defeat the Titans once, but Sackboy accidently reactivated them and now he has to defeat them along with the evil Newton. They may be actual enemies in the game; for example, a giant robot seen in the trailer.
"After the first defeat of the Titans, Swoop retired to the lagoons of Bunkum - spending her days hovering amongst the clouds, perching, pecking and doing all sorts of birdie type things."
On the 17th of November 2014, it was revealed that a total of three Titans will be in the Retail game from the pins section of Lbp.me. Each has a corresponding pin (revealing their existence) which are: 'Titan Tickler', 'Titan Troubler' and 'Titan Toppler'.
