Squids teleport up in the air

Hello, Mojang, I want to inform you about bugs that happened to me relatively recently a couple of minutes ago, so in front of the point I went to the Nizer and took sand from there to bring the visor and remembered that in version 1.13 minecraft sand showers, gives the effect is that objects and creatures rise up from the stream of bubbles. And I had such a problem, I put a couple of blocks of sand in the pond shower. And after a while, the octopus that spawned began to teleport into the air for a couple of seconds, until the octopus was flooded by sand from the soul. I hope I have explained this problem as qualitatively as possible. Oh yes I forgot the version of minecraft 1.15.1 thanks for understanding.
