Badger's Arcane Puppet

You conjure the illusion of an intelligent speaking mobile creature within range. This illusion can move and speak naturally but cannot physically interact with its environment. The illusion does not hold up to physical inspection. A creature can expend an action to inspect the illusion and must make an intelligence saving throw against your spell save DC to determine the falsehood of the illusion. 

While casting the spell you are considered blinded to anything but controlling the puppet. If you lose concentration on the spell the illusion goes slack like a dropped puppet and then disappears.
