Finally got to see an episode from this season today on Sprout, specifically Episode 4276 (The Flood). I really enjoyed it, not only was it nice to see Susan again since she's one of the few humans we rarely see on the show anymore (along with Bob, and sometimes Gina), but the whole story in general seemed to channel older seasons and episodes, such as Episode 3913, which had a similar plot of Gordon and Susan having to continually help Ernie get to sleep while spending the night in Big Bird's nest. Oscar was certainly a beast in this episode, intentionally trying to foul up Maria and Luis's attempts to fix the plumbing, but unwittingly helping out after all by finding similar items they could use to fix the pipes. Not to mention Ernie and Bert's difficulty getting to sleep was very amusing, but in the end, I love how they were fast asleep in Gordon and Susan's bed, snuggling the boogy-woogy sheep, that was adorable.
So, Maria is the building super? Didn't know that.
