Indian tribes?

Homer Simpsons safety gloves?

The Village People?

You've got a start with Homer (though not gloves). Indian Tribes/Village People don't come into it.

But where does Booboo come in?

"did I miss a pic a nic basket

I like Booboo!

...Follow that Granny!

Hawaii 5-0

Homer Simspson's special drinking hat with the straws

*mentally rifles through Homer's wardrobe*

Pin pals bowling shirt?

His big dress/kaftan thing!!!! It was Hawaiin wasnt it?

Places in Hawaii

It was a mu-mu (or possibly miu-miu)

One of topcat's gang was Choo choo (yellow one with a straight hat?)

We've already got Boo boo

Honolulu could be shortened to Lulu

just leaves the 151/ 251.

*goes through the alphabet ..doo-doo, pooh-pooh, noo-noo, tutu...*

anything to do with microcontrollers?

You're on the right lines with your "oo-s", but I wouldn't spell that garment either as "mu-mu" or as "miu-miu".
And Choo-Choo is pink, so that's wrong.
(Go for the Honolulu clue last; it's creaky. We aren't generally Hawaiian here...)

...and forget u-controllers *shudder*

P.

The garment is a muu-muu.

It seems like the similarity so far is a word or name that contains a double vowel, and the first syllable is spelled exactly the same as the second.

Very close. Syllables needn't be identical, though. Double double-vowel is the point.

So the rest are....

*Silliness alert! Or, "summary of a three day backlog".*


Woo-woo!
Ranger Smith got Booboo poopoo on his shoe-shoe. Now he can't go-go to the pic-nic with Tutu is his goo-goo girl muu-muu.

Unlike Clelba, who sometimes says she has nothing to say , I am inclined to say quite a bit when I have nothing to say. Especially when I have nothing to say.

Mooooo! Mooo!

After an hour of deep conversation with the brains of the Weatherwax family, touching on the tao & the chi, never mind the feng shui, Charlie meandered off to watch CBeebies.....

LaaLaa

ah yes, the yellow one with the straight spikey bit.

Thats a double a, a double o and a double u so far. I guess the others will have a double ee and a double i.

teepee
hiiwii
pi ied

I've found pics of Top Cat, and he's the yellow one with a straight hat. He's referred to as T.C. (Tee Cee<?&gt

The yellow one with the straight head-gear is indeed LaaLaa (Teletubby)

Two to go, and they are a double "ee" and a double "ii". (The latter's really clunky, I'll admit. Just you try finding a good one...)
