Great work man, Its pretty fluid. Keep it up.
Nice job on the giraffe and that noise could scare someone if they arent or werent paying attention. (not kidding) How about every time lou blows a raspberry the background changes not still images but moving ones like one second he's swimming with the fishes the next he could be skydiving! And i think if you put the pictures in they should be random so people wont think that the images are predicable.
good idea haha
