That nefarious character Kaptain Kangaroo has been at again wreaking havoc on the poor letter people! In his attempts to take over letter people land, he has captured our friend Mr. N! Lucky for us Kyle Karate is on the job and is hunting him down to save Mr N., Noisy Nose, and return him to letter people land. All of us Top Dogs are practicing our Karate moves and devising plans to catch the dastardly rogue. With the Top Dogs and Karate Kyle working together there is something to fear! Mr. N and letter people land is sure to be saved!
