You do not need an expensive, wooden head ventriloquist figure to effectively do ventriloquism.  Full body puppets, such as the 29 inch People Puppets, 29 inch Bible Character Puppets, Kingdom Puppets, or even Sculpted People Characters are great choices.  Even certain animal puppets can work well, though most people prefer something that covers their arm.  Use any of the above links to view those style puppets or click here to go to the main puppetry page at Children’s Ministry Today.
