28 Sneezes Later and (The) Down With Lee Club.

28 Sneezes Later I liked because it had some major focus on the Tatzelwurm, and the voice acting for him was pretty neat. The cliche 'zombie' b-plot was boring the first time I watched it, but the second time I saw it was on a rainy day and that definitely suits it better. 8/10 episode, bonus points for bringing in the conspiracy.

Down With Lee Club is my overall favourite episode of the series so far, especially the half of the episode where Camilio, Lee and Holger are trying to return Barrage's robotic leg back. There's not really a deep reason why I like this episode, it's just full of shenanigans. 9/10 episode, took away a point because of the show setting Biffy up to look like the mastermind and I knew he wasn't (though my confidence would have made it a much better plot twist).
