Gherkin Gate

The Gherkin Gate is a treasure found in Pikmin 2 at the Perplexing Pool. It is actually the lid for a pickle jar that was made by the real-life company, as the lid for their popular Vlasic pickle brand.

In the Switch port, the treasure has been renamed Flavor Gate. It is an unbranded orange jam lid.

Collecting the treasure
This treasure is found on the mainland in the Perplexing Pool, and is found near the two Burgeoning Spiderworts. It is almost in the same place as the UV Lamp in Pikmin, and the tactic in getting it is just the same. Just swarm Yellow Pikmin against the wall (be sure to have 15 or more). Lead them up carefully through the maze, then throw them up onto the high ledge so they can retrieve it.

Other Pikmin can also reach it with the high ledge trick. On top of that, flowered White Pikmin can slowly move up the ramp if ordered to do so with the swarming function; this will only work with a sufficiently large group.
