In this fourth book in the hilarious illustrated chapter book series, Agent Glyker builds a robot Rabbid and attempts to infiltrate the Rabbids to learn their secrets! When a video of the Rabbids wreaking havoc at a birthday party goes viral, Director Stern of the SGAII-RD (Secret Government Agency for the Investigation of Intruders, Rabbid Division) tells Agent Glyker that this is the last straw--the Rabbids must be stopped! Luckily, Glyker has a new plan: infiltration. Once his robot Rabbid is among the Rabbids and they've accepted it as one of their own, Glyker will be able to figure out what their plan is and put a stop to it. At least, that's the idea... Peek into Glyker's top-secret files and laugh along as the Rabbids stay one step ahead of the poor agent...for now! Rabbids TM & (c) 2015 Ubisoft Entertainment.
