Route 24

Route 24 is the 12th Pokemon Tower Defense level. It is heavily based on the Nugget Bridge.

This level is different from the others. You have to fight 5 trainers in a row, first preventing them from crossing the bridge with their pokemon, then attempting to cross the bridge with yours. The mechanic is similar to the Old Rod challenge.

Suggestion
For the second part, (the one which you have to send your Pokemon to grab the rare candy) just throw out all your best Pokemon and you'll win. You can also use an Arbok with Stockpile for higher defence. For the latter levels, when you must defend against 1 or 2 pokemon, you may want to use a pokemon that knows the move Roar. Arcanine and Vulpix will already know this move when captured from Mt. Moon 2.
