If your liard dies all of a sudden, it probably means that either it was sick and didn't tell you, or it was sick and you weren't paying attention. If you are unsure, look at the variables and if they are below 30, try giving it medicine ESPECIALLY AFTER IT WAS FAT BECASUE THIS MAKES IT LESS HEALTHY!!! (click and drag the shot) Press H and S to hide and show the variables. This applies to all of my pet lizard games. Lizard not moving after it wakes up? Click "see inside" and go to the "backdrops" to fix this! You can drag your lizard around to move it, and use O and P to rotate it! This can be used to set it somewhere while it sleeps! Care for your very own virtual pet lizard! Feed it, give it water, play with it, care for it, clean up after it, all that. Keep him healthy, make sure that he doesn't die or run away. Click on the lizard manual to learn how to care for the lizard. Everything you need to know is in there. Arrow keys to turn pages, B to close book. You can also press h and s to show and hide the variables. Enjoy:)
Sometimes there will be a glitch where the lizard moves around in its sleep. Just hit the stop button n=and try again until it doesn't move.
