Ben 10: Power Trip

For those of you who did not collect the Wurst on top of the tower during the main story quest.

There is a building beside it that you can grapple up and use diamond to surf across to over the the grind rail. Below is a quick video that shows it.

Let's start with a warning, I believe this achievement is missable. Because 1 of the sausages you have to collect for the activity The Best Wurst can become unobtainable. It's the sausage in the tall circular building in the middle/bit west of the middle of the city. You can only enter this building as part of the main quest. It's where you learn the Shockrock form. When you find yourself in this tower and you can turn into Shockrock go ALL the way to the top outside roof of the building. There's a sausage there.

Also 1 record and 1 trinket didn't show on the map for me, even though I bought all the maps. If you have the same issue, the record is probably in the triangular park in the SW part of the city. Move some blocks with fourarms and use Heatblast double jump from the tall block to reach the record. The trinket will be a postcard on the railroad in the east part of the city. Just follow the railroad from the city towards the forest and you'll find the trinket on the railroad near the castle
