After such a good boss battle, you level up your echelader from BABY'S FIRST CASE to BASICALLY A NOOB. Not much of an improvement, but a good one noneththeless.
The echeladder is this game's version of a level up progress meter. You're in a sense, level 2, but you could be as big as 16. You now have the ability to see through walls for 5 seconds, and then you have a cool down of 30.
You also gained 250 Boondollars.
What are boondallars? Well timmy, Boondollars are this game's ingame currency, used to buy things like weapons, armor, and special moves. Each level up of the Echeladder contributes a little amount of Boondollars to the Porkhallow. The Porkhallow just keeps the money, while you're left to adventure til your heart's content. Once you have a million Boondollars, you can exchange it in for Boonbuck. Alright little billy, now you know what Boondollars are, and you too can be a good member of this society.
After collecting a bunch of build grist, you talk to your client again.
PI: did you see that
SB: Yeah, you destroyed those two Ogres and Lich. Now you have a bunch of Grist.
PI: are you gonna build with it
SB: Yes, I will now build some stuff with the Grist you got.
You then head back to your house, shooting a few imps on the way.
