Sealand was aware of everything that happened around his fort, and he loved it. He pointed out the names of fish to Chibiusa, described the birds, and expressed a simple, childlike joy in experiencing nature so acutely.

Chibiusa didn't know so much about the birds and fish, but when she saw them she was happy, and because Sealand was excited while he was explaining everything about them, she was excited too. Because Sealand wanted to show her the changes of the seasons so she could see whole different sets of fish, she had to be invited back, to nobody's dismay.
