Lem and Ada (a pun on lemonade) are twin brother and sister, from England's "Pickle-Dilly Circus", a parody of Piccadilly Circus. Although the same size as other babies in the series, the twins seemed to be especially precocious. Not only did they speak quite well, they even finished each other's sentences. Although it is fairly obvious by looking at them which twin is Lem and which is Ada, apparently telling them apart was problematic for those who lived in Strawberryland. Only their pet sheepdog Sugar Woofer seemed to know for sure.
Although the same size as other babies and toddlers in the series, the twins seemed to be especially precocious. Despite being so young the twins can speak formally and quite well, and are known for finishing each others sentences. This implies that the twins may be pretty smart, as they are also capable of doing the tasks other young ones cannot. Though, they still crawl sometimes.
