Use a text editor to edit the "proto.xml" file in the "data" directory in the game folder. Note: You may first need to uncheck the "Read Only" attribute of that file's properties in Windows Explorer. Search for the text "CrateOf". You will find CrateofFood, CrateofCoin, CrateofWood, CrateofFoodLarge, CrafteofCoinLarge, and CrateofWoodLarge. For all these entries, find the tag "InitialResourceCount" and change the count to whatever desired. For example, the normal crates each have "100.000" of the resources. You can change the "100" to "99999.000", etc.

First, place a unit on the map, then select the "Replace Unit" command under "Objects." In the drop down menu, select Fluffy, Flying Purple Tapir, Learicorn, George Crushington, Lazerbear, or Monster Truck A and then click replace unit.
