Squirrel Chin Ups

This is version 4.2 of the squirrel deterrent system. It will be henceforth renamed as the Squirrel Wipeout Exercise course.

The spinning white tubes are effective in preventing a casual stroll to the Discs of Intimidation. Which, after a few days, aren't so intimidating anymore, as the squirrels have learned to sprint across the cable, dance along the tubes and simply tackle the discs head-on. If there's enough momentum (and a fair bit of balancing) Mr Squirrel can gain access to the Castle of Plenty.

Version 5.0 already in the workshop.
