When Euru, Acorn Scrounger enters, you may forage (To forage, exile three cards from your graveyard or sacrifice a Food.). When you do, conjure (A conjured card is added to the game.) a card named Chitterspitter onto the battlefield. Whenever one or more Squirrels you control deal combat damage to a player, you may sacrifice a token. If you do, put an acorn counter on each permanent you control named Chitterspitter.
