I held a small amount of Solana in my Binance account and got a Pudgy Penguins (PENGU) airdrop automatically.
But I hold most of my SOL in a wallet and didn't get anything for that.
It took me some time, I'd had more wine than usual than day, but then I had an 'oh s**t' moment and realised maybe I had to manually claim it.
And I was right.
I claimed PENGU and got enough for more bottles of wine.
Which is great, but, if you hold Solana, don't forget to claim your PENGU.
It is apparently also available to ETH holders, but I'm not sure how that works, because I hold a lot more ETH than SOL, but got zero PENGU for my ETH.
