The Numbers Audio LED Tree plays the numbers 1-20 (unlike most toys, which go from 1-10). Children can follow along with the pictures in the activity book, "My Numbers Story Book." There are three (3) parts to the song, the first part is in English, the second part is in Spanish, and the last part of the song in both English and Spanish. The tree also has seven (7) soft LED lights, which can be turned on or off separately from the audio button. This huggable audio tree is produced by Blue Diamond Publishing and contains the company's logo on each product's tag. The idea of this tree came from its accompanying book mentioned above. This lovable Plushie is perfect for your little children to learn numbers in both English and Spanish. It is the perfect gift for any occasion and requires three (3) AA size batteries.
