What is this and how is that even possible?

I was looking through some memecoins (shitcoins really) trades just trying to understand the logic and some mechanics of how does it work. One thing I don’t understand in this example is these couple of strange trades (https://imgur.com/a/az5Iajc).

See how first the liquidity is added to a Raydium LP. Then there are several trades. And then those two traders interact with an unknown platform by swapping 25 and 5 SOLs for this new token at a much lower price (nearly 10x lower) than the actual price in the Raydium’s pool. How is that even possible? Is that some custom Program with its own pool that just has a different ratio of SOL/token deposited there?
