Maquette

This takes place in the 3rd level The Gateways. As you progress through the level you will find a golden key in the green house that you will use to open a door in the sand area. Take the green crystal to that door. Right before you cross the barrier turn right and jump on the ledge of the building and walk along it to the bridge. Halfway down the bridge is a break in the wall and a rock. Jump across onto the rock, on top of the rock jump over the wall. Go straight ahead and you should see a giant green barrier. Walk through the barrier and into the doghouse.

Just to add some clarity to what is written above/below. Once you have progressed far enough so that you have used the golden key, inserted the small red crystal inside the buildings circular hole (on the side) on the smaller model map and then gone to the normal sized beach palace with your green crystal, you are then at that point able to activate the bridge. Once done so, this is where you should save (just in case), because if you touch the cog on the other side of the bridge, the central pavilion becomes locked off/ another structure and if you try to escape the map you still won’t be able to access the much larger green house and the dog kennel therein. Once all this is done get on the bridge using crystals or just jumping round the corner, jump from the mid-point where the wall is broken to the rock structure, then to the towelled wall, and head straight for the large green house in the larger distance, there is a small mouse hole crack to walk through so you won’t need the green crystal to unlock any barriers, directly in front is the dogs house/ kennel walk in now that you are small and look around. Chievo pop!
