Sitio do Picapau Amarelo Master System

Tia Nastácia (Aunt Anastacia) is sick, and Dr. Caramujo (Dr. Snails) is called to examine her. And he's got some good and bad news. Good news is that she can be cured. Bad news is that, to prepare the medicine, he'll need five rare ingredients: bat's blood, Saci's hat, Curupira's salsaparrilha bat, Iara's hair and a tear from Cuca. To make things even worse, next night will be a full moon, and if Tia Nastácia doesn't get cured until then, she'll sleep for 100 years! So, Pedrinho (Pete) and Emília (Emily) are sent to bring the ingredients and cure Tia Nastácia.

Sítio do Picapau Amarelo (Yellow Woodpecker Ranch in English) is based on the works of Monteiro Lobato, a Brazilian writer. One or two players (in hot-seat mode) can choose to play either the boy Pedrinho (or Pete, in the English version of the books) or the rag doll Emília (Emily in the English version). The items they must gather are based on Brazilian folklore.

Gameplay consists in basic side-scrolling/platforming. Either characters can jump (button 2), run (either pressing the D-pad twice to a direction, or holding a button and the D-pad to a direction), shoot (button 1), and duck. The game has four levels (one for each ingredient, the last one with two of them), all set in the ranch, with indoor levels, underwater levels, caves and such.

Each character starts with 3 lives. They have a health bar, which can be replenished by gathering items such as nests with eggs, or by freeing birds from cages. The enemies faced are most animals, such as bats, bugs, spiders, snakes, piranhas, jaguars and monkeys.

All in game text is in Portuguese.
