If you've been paying attention to your Sakana lore, you'd know that Sakana's favourite anime is Gundam Seed. I didn't think much of that when I first heard that. But I'll share a few tidbits that might be of interest:
1) Phase Connect was named after the Phase Shift Armor featured in Gundam Seed.
2) Sakana's anime oshi is Lacus Clyne:

She has long pink hair, and is an idol and pop singer. I think it might be a bit much to compare Lacus to the moldy rabbit, but there are several comparisons that could be made. He has said that he's making an idol company though.
In any case, Sakana started a vtuber company to make more girls like his anime oshi. I kneel.
