Part 16 of my Random Dungeon series shows you how to build a fire barrier that only your sidekick can deactivate. Players must throw their sidekick through a special sidekick door that will then turn off the barrier. This kind of obstacle is frequently seen in toy box games like Brave Forest Siege, Escape the Kyln, and Toy Box Takeover, so now you can see how to build it yourself!

Here is the logic diagram for connecting the Creativi-toys that were used to build the fire barrier puzzle.

Enjoy!
