      The bug

      Squids choose the direction they are simming in randomly. This means that they sometimes also try to swim "through" a wall. Whereas other mobs trying to walk against a solid wall just collide with it, squids sometimes glitch into it (maybe client-side only).

      The reason

      The following is based on a decompiled version of Minecraft 1.10 using MCP 9.30.

      The reason might be that the class EntitySquid is overriding the method net.minecraft.entity.EntityLivingBase.moveEntityWithHeading(float, float).
