The top left one requires you to turn off all the radios.
The top right is more complicated and requires a lot of steps. You can start by opening a locked door in giraffe town with the key you got from the superstructure basement.
then you need to draw 3 or 4 white lines on the pad in following rooms: purple room in superstructure floor 2, da room with da key, cuttycraft in the floor 1 of superstructure (the place where you place blocks with grimcutty writed on them), superstructure floor 1 itself, golden city skies, gentles and finally after you collect all of those 6 diamonds: with that treasure, you can summon mahor- i mean LD, draw 4 lines in the Car0 area and then everything will turn black/white and the Lost Dog will appear... you need to touch him and he will take you to the place where you picnic with him and it counts as the "True Ending"
