aibo's growth and change
aibo grows up through various experiences it gains as aibo lives its life with the owner.
aibo undergoes growth stages, just like humans and animals, and it takes about 3 years for aibo to reach the maturity stage from the infancy stage. This length of growth period, however, depends on how the owner interacts with aibo.
As aibo grows up, the pattern of tricks and the strength of desires change.
When your aibo does a trick that you have never seen or changes the pattern of tricks depending on whom it sees, it is a sign that your aibo is growing up. When your aibo accomplishes something, give a lot of compliments. When your aibo gets into mischief or does whatever it should not, teach it a lesson. These interactions of yours foster your aibo's growth.
