Guys! The maintenance bay of transformers is at least 20-30ft underground. Not a problem at all. You also have to realize, that part of the park is built up a little when it was originally designed. That's why you walk up hill from Marvel to Toon. Think of it this way: What we're calling ground level in the KONG area is level with the RIPSAW FALLS bridge but the boats go under that bridge. Add the channel that the boats sit in you got at least 25 ft to play with. Which is 2 stories. There are deep trenches already dug in the area. And they could go a lot deeper if they wanted you just have to reinforce the walls like they did for transformers.
