The Bad: The humor in these (very short) episodes is very hit-or- miss. The direction of the episode (or the conclusions) can be predictable (for an adult). Some episodes are pretty intense (the threat of danger for the animal in the episode can be high). Zero level of educational value.
The Good: The cartoonish animation holds up fine. Although you can't expect realistic fur or movement, it isn't so blocky as to be distracting. The music is fine and conveys the emotions well. There is no speech (even with the humans), which works well.
Mom View: Pre-school friendly episodes. My son didn't mind watching these, but he didn't love them either. Some episodes got smiles and others he seemed to find disturbing due to the distress of the episode's animal. Overall I'd recommend this to kids of all ages (who aren't especially sensitive), but don't think it's worth buying or going out of the way to find.
