Littlefoot's first toy. It's obvious how much sentimental value his tree star possessed, and it was a tragic moment in his life when it got destroyed. This tree star, while not quite the same, reminds him of the one his mother gave to him as a hatchling. To paraphrase Ducky123's quote for today's standard...
A simple toy does the trick as well.
Unfortunately, with the average human attention span less than a goldfish apparently, children today
live on technology.
