# 711 Turn all his living tissues invisible. This does not include skin, hair, or nails, but skin is translucent, and he can always shave everywhere.
# 712 Identify the sex of a frog on sight
# 713 Turn any wizard into a squib, permanently. Only works during a total solar eclipse.
# 714 Eat books to magically memorise their entire contents. Understanding them not included. Acceptably small risk of insanity.
# 715 Detachable feet. They can shuffle round without him, though their only sense is touch.
# 716 Knows exact age, weight, and measurements of anyone he kisses for at least seven seconds.
# 717 Turn himself into a statue. Transformation only reversible by a kiss, but anyone will do.
# 718 Animate any wooden object. They get a copy of his personality, but aren't under any control.
# 719 Step into, and out of, any picture.
# 720 Turn broccoli into liver.
None of these are completely useless, though most of them would require rather bizarre circumstances.
