The faltering Chia Pet

Some dedicated Blippers may recognize the face of "wee" Bob who has grown up on this public forum. Bob received a Garfield Chia Pet for Christmas. The Chia Pet's growth, while prodigious at the start, has faltered. Well, it is now mostly dead. The Garfield Chia Pet now has dried dreds. However, Bob's fascination with it has not dimmed. Perhaps the Chia Pet was not meant to sustain life past 3 weeks. Has anyone had a similar experience?
