Probably "Eggs". Think it might be the tune, but I'm not very fond of it.
On the flip side, "Eggs" does establish the difference between Ozzy and Strut as much as "Who Needs You" quite underscores why Dil and Ichy don't get along so well and also serves a useful purpose. However, perhaps the tunes are annoying.
I love the tune of "Friends for Dinner" though I admit, the mental pictures it gives are, er, disturbing. i.e.
Cera
You won't think it's funny,
When he chews on you.
Cera
He'll munch and he'll crunch
Those little duck feet.
Petrie
If he just eats Spike,
Wouldn't that be enough?
(That one actually was pretty funny.

)
Ducky
He would spit out Cera,
'Cause she's too tough!
Cera
Spoken:Hey!
(That was even funnier!

)
Ducky
We'd rather sink in the mud,
Petrie
Fall out of the tree,
Cera
Roll like a rock
Right into the sea.
(Are they saying they'd rather kill themselves than be eaten???? :blink: :blink: )
Cera
He'll gnaw your arm
And he'll nibble your leg
Petrie
He'll bite off your beak
Ducky
That would hurt
Chomper: I wonder if this tastes good. (Puts green food in his mouth and eats it or tries to)
All of them: Yuck!
(Hilarious!

)
On the flip side, Littefoot is really showing his loyalty to Chomper despite the doubts of the others, particularly Cera. (Who, soon, will show her doubts outloud to everyone, including Chomper. It is quite obvious from this song that she really distrusts Chomper the most of all of them.)
Littlefoot
He just wants to have
Friends for dinner.
Littlefoot
That's not a very nice thing to do
Littlefoot
He can't eat vegetables,
Only meat.
Littlefoot
But we've known Chomper
Since he was an egg
All in all, still loved the song. Liked it too in the "Brave Longneck Scheme" (which, thankfully, other than the "I wonder if Rhett tastes good. (Not that I'd mind if he ate Rhett.

) , was much less graphic word imagery wise)
Also, I am not a fan of "Lone Dinosaur" either, or indeed most of that entire movie. However, there were the lines, that went something like:
Cera: We'd better be back. You don't want to see Grandpa Threehorn mad. He can be as a mad as a......
Dana and Dinah: (Spotting a Sharptooth) Sharptooth!
Cera: I don't know about that. Well.....maybe.
That was hilarious!
I really don't dislike too many LBT songs.
