Walmart offers the Fisher-Price Imaginext Eagle Talon Castle Dragon, model no. W9554, for $16.25.
(Amazon charges the same with free shipping for Prime members.) Opt for in-store pickup to dodge the $4.97 shipping fee. That's $9 under our mention from last fall and the lowest price we've seen. (It's a current low by $38.) It features sound effects and light-up features and will interact with the Imaginext Eagle Talon Castle (not included).
