Kong Bananza: City Smash is the first Challenge Course for the Canyon Layer in Donkey Kong Bananza. This one tasks you with demolishing a building fully, but you have to do so within 60 seconds. Worse, you actually need to be even faster than that if you want to get 100% for this stage! Fret not, though, this guide will tell you everything you need to know to accomplish that feat.

For this level, you can get two out of the three Banandium Gems by simply getting the destruction to 100% in under 40 seconds. If you take longer than 40 seconds but less than 60, you’ll only get 1 banana. So, try to be speedy to get both at once!
The best way to clear this challenge is to focus on the internal pillars of the building. They get the percentage up fastest. Once you break a pillar, just continue looping around the building while breaking down walls as you move towards the next barrel. Just don’t focus on the walls too much and stay on the move!

If you do this right, you should be at around 70% or more destruction by the time you reach the third floor. Break the large central pillar on this floor as fast as you can! It should take you from 70% all the way up to 100%, completely demolishing the building and finishing the challenge.

So, if you had 20 or more seconds remaining on your timer, you should be eligible for both Banandium Gems. They’ll be by the level’s entrance, so you just need to smack them to collect them!

As for the third and final Banandium Gem, you just need to dig the dirt under where the central pillar used to be. It’s the only patch of dirt in the whole level, and it’s right in the middle of it, so it’s hard to miss.
There you have it! That’s how to 100% and collect all of the Banandium Gems in the Kong Bananza: City Smash level of Donkey Kong Bananza. For more help and a little nostalgic trip, check out our guide on the Nostalgia Country level as well.
