Sonic's Chao Garden

Sonic's Chao Garden is a term used to describe the Chao Garden raised by Sonikku Yujinaka. Beginning in the Chaos Arc, Sonic would use the Station Square Hotel's chao garden and raise several chao before transporting them to the Chao Lobby. Sonic has maintained and frequently visits the garden to take care of the chao he owns.

History
After his first skirmish with Chaos 0, Sonic visted the hotel he rented when he was told about the Chao Garden, a resting spot for the intendees to play with the numerous Chao. Upon reaching the garden, he discovers that no Chao are in the garden, but several eggs are sitting on the floor. Later on, he'd learn that the Chao in the garden would be abused by careless kids and adults, causing them to sadly pass away without reincarnating. It's implied this would be the reason Sonic takes care of the Chao Garden, as the hotel workers would remark about Sonic's frequent visits back and forth into the garden, using his accumulated rings to get food for them. When Knuckles and Tails open the portals to the other gardens, Sonic uses these to raise even more chao.
