Mr. Pignati told the kids to take care of two things until he returned. What were those two things?

At the hospital, Mr. Pignati asks Lorraine and John to take care of his house and Bobo (the baboon at the zoo).
Bobo is Mr. Pignati's favorite animal at the zoo. Since Mr. Pignati is in the hospital, he will not be able to visit Bobo until he is released. As a result, he asks John and Lorraine to feed Bobo properly when they next see him at the zoo; they are to make sure that Bobo gets dry-roasted peanuts from the yellow package (not the red package) and half a hot dog. Mr. Pignati tells John and Lorraine that Bobo never eats the whole hot dog.
Mr. Pignati also tells the teenagers to take care of his home. He invites them to make themselves at home in his house and to use anything there they want. John and Lorraine take Mr. Pignati up on his offer, but their good intentions are soon obscured by their desire to have fun. They hold a party at Mr. Pignati's house, and a terrible fight breaks out between John and Norton (a classmate), resulting in the destruction of many of Mr. Pignati's pig figurines.
Mr. Pignati never fully recovers from his grief and later dies from a second heart attack.
