The seventh series, which is once again aimed at five- to six-year-olds, comprised five episodes focusing on how to add and identify two-figure numbers up to 100; each episode would open with Bill and Bernie, whose number line had been replaced by a number square, and joined by a caterpillar named Limo (voiced by Peter Temple), who would crawl around the square to count out the numbers they required. In Santo Flamingo, Maria's sister Pepita Consuela Tequila Chiquita also started at San Flamingo School.
