I believe the character is Osprey from this tweet by teranekos, but the google translated commentary is hard to understand.

@Moonspeaker FYI this is why I changed your translation of "お魚好きそう":

The auxiliary verb そう(だ/です) has two different meanings: hearsay (伝聞の「そうだ」; your translation) and appearance (様態の「そうだ」; mine).

The former follows the conclusive form (未然形) of a na-adjective (形容動詞) (e.g. 好きだそうだ) while the latter follows the stem of a na-adjective (e.g. 好きそうだ).

In this case, the "好き" is word stem, so the そう means appearance rather than hearsay.
