Rope is an item featured in many Humongous games. It made its first appearance in Putt-Putt Saves the Zoo.
Putt-Putt will need rope in order to rescue Kenya the lion cub. Putt-Putt can find some rope in the igloo located in Arcticland. Once Putt-Putt has the rope, he can use it to rescue Kenya from the ledge she is stuck on (Putt-Putt will need to rescue Kenya from above in order to rescue her).
In the demo, on the other hand, the rope is already in Putt-Putt's glove box.
The rope is one of five possible items necessary for the trap. The rope is located outside Captain Schnitzel's submarine, but it's tied up in a knot and Captain Schnitzel doesn't know how to untie it. To get the rope, Freddi and Luther will need the Book of Untying Knots (found in the sitting room, which is above the room where the cork could be) in order to find the method to untie the knots of the rope on the anchor. Untie the right knots, and you'll obtain the rope (which replaces the Book of Untying Knots).
There is a rope attached to Ms. Tree and is used by the Custom Inspection trees as a booby trap for Sam, allowing them to take his things. After he gets down by the player clicking on Sam, Ms. Tree lets Sam borrow the rope. Sam can then use the rope to retrieve the wooden plank from the river, but he loses the rope in the process.
Putt-Putt will need the rope if Tobias T. Train needs to fill up on water. Putt-Putt can find the rope within Virgil Clyde's barn. Putt-Putt will then need to use the rope to grab hold of the water tower spout and pull it downwards so that Toby can fill up. After that, Putt-Putt will let go of the rope, which will cause the spout to send the rope flying away.
