Sr. Mistu ran out of olives for his pizza. What will he do? What anybody would do: embark on an epic journey that will take him around the world... and maybe further away. Isn't he brave?
You and Gaido (his little guide dog) will go with him in this adventure. First, you teach Gaido the path and then, he walks Sr. Mistu through the level. This is team work!
