While your animal companion is wearing this collar, you can use a bonus action to speak the collar's command word and cause your companion to assume the appearance of another creature. You decide what your companion looks like, including color, form, and clothing, but the companion retains its normal size, bulk and weight. You can't change the companion's body type, so you must choose a form that has the same basic arrangement of limbs. Otherwise, the extent of the illusion is up to you. The illusory appearance lasts until you use this property again or remove the collar.
