That was ace.
By far the best of the series. Unless Episode 5 beats it, of course. Loved Superball again, mainly because he’s so deadpan. The mariachis were all sorts of amaze, and the Max/Ms Bosco “relationship” was fantastic. The baby making machine, and the various possible Bosco outcomes awesome too.
And, best of all, it relied upon proper, logical puzzles instead of try everything on everything puzzles. Yay!
