I have this for number #2
I had to put { } around it
// The short JSON file called "data.json" is parsed
// in the code below. It must be in the project's "data" folder.
JSONObject json;
void setup() {
json = loadJSONObject("data.json");
JSONObject id = json.getJSONObject("blocks");
println(id );
println(id.size() );
JSONObject animal1 = id.getJSONObject("vJb19r)WPw88AL7K#^ZI");
println(animal1);
//String species = json.getString("species");
//String name = json.getString("name");
}
