Trinkets

Trinkets are a type of passive item that can be picked up and dropped at will added in The Binding of Isaac: Wrath of the Lamb expansion. The ability to drop trinkets after picking them up was added in The Binding of Isaac: Rebirth. The Tick trinket, however, is still permanent once picked up. Trinkets add passive bonuses to the player, but can only be held one at a time, unless the item Mom's Purse is collected. This item allows two trinkets to be held at once, though they cannot both be the same trinket.

Liberty Cap	Touch fuzzy get dizzy	Randomly adds a mushroom effect in different rooms. The text "touch fuzzy, get dizzy" is a reference to the name of level 7 in world 1 of Super Mario World 2: Yoshi's Island. In this level, Yoshi is faced with the enemy "Fuzzy", and if he touches one it makes a distorted exploding sound and causes Yoshi to get extremely dizzy, difficult to move around and jump, and hallucinate that the environment is distorting as though he was under the influence of a powerful drug.

Monkey Paw	Wish Granted	When the player is reduced to 1/2 heart of health, Monkey Paw generates a sin heart and the image of the trinket changes from an open hand to one finger down to two fingers down. When the Monkey Paw is activated for the third time, it disappears completely. Dropping a partially-used Monkey Paw will show the default, open-paw image, but once it is picked up it will resume the form it had before it was dropped. The Monkey Paw is a reference to the short story W W Jacobs, in which a man receives a monkey's paw from a house guest, which grants him three wishes, resulting in the death of his wife and child.
