Bloo wakes up one day to find the Foster's Home completely empty, and after Mac arrives they discover everyone went to the beach without them. However, this presents a golden opportunity, as until they get back, they have free reign over the place! The real problem is, how can they use the time they have to do the "Most Awesome of Awesome Things" when they have no idea what would even count for that?
Tropes:
- Answer Cut: After realizing the entire Foster's House is empty, Bloo shouts "WHERE IS EVERYBODY?!?". Cut to everyone at the beach, having deliberately left Bloo behind.
- Bait-and-Switch: One scene shows what looks like Mac and Bloo taking rapid-fire selfies of them making goofy faces, but it turns out it's actually both of them rapidly messing with the lights and posing about.
- Call-Back: When searching for Madame Foster's hidden treasure, they come across a chest filled with more of Uncle Pockets' heirlooms, showing he's buried more than what was shown in "Bloo Done It".
- Comically Missing the Point: Bloo initially doesn't realize having the Foster's Home all to themselves gives them the freedom to do whatever they want, saying "I already watched TV." and leading Mac to have to spell it out for him that there's no rules with Herriman and Frankie away.
- He also thinks that a compass that points North is useless in finding which way South is.
- Elevator Floor Announcement: Bloo does this on their way upstairs as they stop at every floor after he pushed all the elevator buttons.
- "Everyone Is Gone" Episode: Bloo wakes up only to find out that everyone who lives at Foster's is gone. It's revealed very early on that everyone went to the beach without him to keep him from ruining their day. Unfortunately at the end of the episode, it turns out that Fosters doesn't need Bloo for something bad to happen.
- Gave Up Too Soon: In a last-ditch effort to do something awesome, they try to find Madame Foster's hidden treasure and dig up all over the yard, and find a chest, only to discover it's filled with more trinkets of Uncle Pockets. The Stinger at the end shows Madame Foster discovering all the holes and pulling the real treasure out of one of them.
- Irony: Everyone left Bloo behind so that their day at the beach wouldn't get ruined by his antics. It gets ruined anyways, and it's Nice Guy Wilt who's guilty for it.
- Laborious Laziness: Bloo drops a potato chip on the floor and goes to monumental effort to avoid being the one to pick it up himself, running all about the house trying to find someone else to do it only to keep discovering the person he's trying to find isn't there at all. He runs by the same chip several times in the process, and is left exhausted by the end when he gets to the last person he can think of asking, Never-Leave Steve.
- Noodle Incident: We don't know what exactly it was that Wilt did that got all of Foster's blacklisted from ever going to the beach again, but Frankie mentions that she has to go back to clean up all the sand, and find homes for all the jellyfish.
- Not Helping Your Case: At the beach, Frankie says that Bloo would ruin their time, so they left him behind on purpose. Once Bloo finds out through a note Mac finds that they've gone to the beach, he wonders aloud why they'd go without him:
- Bloo: Why would they go without me? I'd be loads of fun at the beach! Splashing people, putting sand down people's shorts, screaming "shark!"
- Not So Above It All: When left in Foster's alone with Bloo, it's Mac who decides to go wild.
- O.O.C. Is Serious Business: As Bloo notes and the name indicates, Never-Leave Steve never leaves, and yet Bloo finds he's gone too.
- Bloo: Wait a minute! Never-Leave Steve never leaves! WHERE IS EVERYBODY?!?
- Wilt somehow ends up causing trouble for everyone at the beach and winds up geting them all banned, and all he can say for himself is that he wasn't sure what suddenly came over himself.
- Overly Long Gag:
- Bloo running about the house to find someone, only to not find them in their usual place. Each time, he adds the last person he tried looking for to the list of who's missing, only to realize the next person he's asking for is also missing, upon which he says their name in an increasingly higher-pitched tone. By the time he gets to Never-Leave Steve, he's exhausted listing everyone he couldn't find, and makes a high pitched squeak when saying Never-Leave Steve's name.
- "It's hot in topeka."
- Persona Non Grata: Whatever Wilt did, it was so bad that it led to the governor banning the whole of Foster's from the beach.
- Real After All: Bloo believes that Madame Foster has buried treasure from her "pirate days", though Mac is skeptical until they discover a map hidden behind a portrait of her. And the Stinger shows she indeed had buried treasure in the yard.
- Series Continuity Error: Mac's seen eating a large number of sugary foods with Bloo when the house is left abandoned, yet he never goes into a sugar craze, and in fact suffers a Food Coma instead. Though it is possible that he simply was picking the sugar-free versions of the items he consumed (whipped cream, jelly, ice cream, etc).
- The Friend No One Likes: This episode above all else shows how no one really likes Bloo; everyone arranges a trip to the beach and deliberately don't tell Bloo about it, only leaving a note for Mac to find. Bloo is rather incredulous that they'd go without him.
