Catch spinach cans! Besides filling the belly a little bit, they allow (for 10 seconds) Zampo to kill the baddies and, as a prize, earn a full refill of belly and turbofart charge! This is the so-called PIG-OF-STEEL mode.
When Zampo takes a rest on top of some peculiar zone-specific tiles, he becomes golden, faster and immune to the Evil Masters. Make the most of this PIG-OF-GOLD mode and beware: if Zampo touches something dangerous, he returns normal.
Whenever you get a chance, operate the switches, as they open the barriers and/or build the paths that will give Zampo access to new areas (maybe later on).
Use the turbofart to land on otherwise unreachable places. To recharge it, catch the Gasorade bottles or kill baddies by means of the PIG-OF-STEEL mode.
If you are stuck or need to return quickly to (a place close to) the active checkpoint, touch an Evil Master or something dangerous - witch Cotechina will take care of the rest ;)
