- Going strong after more than 50 years, the Berenstain Bears still have some adventures ahead of them and some lessons to learn. In these tales for readers and listeners 4 to 8, Brother and Sister Bear discover the importance of keeping their room clean; the whole family realizes that they are watching too much TV; the bears start eating healthy foods; and the kids are cautioned about strangers. Stan and Jan Berenstains" bright illustrations continue to evoke the good-natured humor of 1950s sit-coms.
