Animate Dead Beasts

This spell creates an undead servant. Choose one or two piles of bones or corpses of a beast of CR 0 that is within range. Your spell animates it as a skeletal animal if you choose bones or zombie animal if you choose a corpse. Such a creature has the same statistics of a living creature of the same type, with the following changes:

Skeletal animals have Intelligence 1 (-5) and Charisma 5 (-3), unless it was already lower, are vulnerable to bludgeoning damage, immune to poison damage, exhaustion, and the poisoned condition, and have darkvision to 60 feet. The skeletal animal's type changes to undead.

Zombie animals have Intelligence 1 (-5) and Charisma 5 (-3), unless it was already lower, are immune to poison damage and the poisoned condition, and have darkvision to 60 feet. They also have the Undead Fortitude Trait. The zombie animal's type changes to undead.

As undead, the creature doesn't need to breathe, eat, or sleep, and it loses any trait, such as Amphibious, that assumes a
living physiology. On each of your turns, you can use a bonus action to mentally command any creature you made with this spell if
the creature is within 60 feet of you (if you control multiple creatures, you can command any or all of them at the same time, issuing the same command to each one). You decide what action the creature will take and where it will move during its next turn, or you can issue a general command, such as to guard a particular chamber or corridor. If you issue no commands, the creature only defends itself against hostile creatures. Once given an order, the creature continues to follow it until its task is complete. The creature is under your control for 24 hours, after which it stops obeying any command you've given it. To maintain control of the undead animal for another 24 hours, you must cast this spell on the creature again before the current 24-hour period ends. This use of the spell reasserts your control over up to four creatures you have animated with this spell, rather than animating a new one. You can also reassert control of undead beasts by casting animate dead on them.
