Yellow cubes shoot bullets too fast that most of the time they hit the character so no one is encouraged to attack them, you lose more than what you can gain, assuming that they drop a meat piece of course to recover part of your life, otherwise the fight is completely worthless. A trick to kill them “more safely” 😒 is placing at least 2 blocks in front of them and killing them from a side or trapping them with blocks by creating a small block formation around them (but it's a nice tactic against almost any enemy from other mods 😉️). 4 pillars 2 blocks tall around them is enough. Bullets fly through blocks corners though so mind where you stay. Also, once enemies are hit sometimes they do a sudden dash to the character making fights risky in any way you engage them, I've fought enough to see them dash so fast that they run through the character and I find them behind him or I'm attacking them and continuously pushing them away but their glitchy movements waste my fights because they seem teleporting from a point to another. I feel that a part of a soundtrack is from Halo: Combat Evolved 🤔️.
