Kollin's Crazy Awesome plan to snap Jeff out of being Distracted by the Sexy. He hacks into a poker machine just to get $999999 to bribe the dresser Jeff is ogling to strip off all her feathers (which is considered highly unattractive by maniraptors), and when he ends up with $1000000 instead, he goes the extra mile to spend that one excess dollar. And not only does the plan work, after all that Kollin, Corrie, and Jeff only arrive at their planned rendezvous point slightly later than the others.
Cyryl's hidden arsenal of drugs and poison in his mouth, all concealed by his teeth.
Which he shortly uses to knock out Rob and Langsty when they catch up with Jeff.
Primus's life story. After traveling to the Late Cretaceous, he eventually became one of the most powerful figures in its society, all without being a troodont.
Kollin trying to shake off a pursuing Beelzebufo by getting it run over by a bus, setting it on fire, and blowing it up with a bomb. Sadly, the Beelzebufo turns out to be a Super-Persistent PredatorMade of Iron.
Corrie tricking said Beelzebufo by drawing a hyperrealistic replica of Kollin in a time span of what seems to be just a few minutes.
Sampson, after being something of a Butt Monkey in earlier episodes, comes back to life in "Soaring Pteros", mutated into a Jurassic Park-style deinonychosaur, and goes onto free the others from Djhey Pterus and defeat the mad scientist. This also leads him to become braver.
Kollin's rant in "Permian Safari is Nudist".
"Planet Not-Theropod" is filled with these:
The various ways the non-troodont maniraptors escape being tranquilized in part one. Kollin outruns the tranquilizer darts, Corrie diverts them with a decoy, and Kim-Lee's plumage turns out to be too thick to be penetrated. Meanwhile, all the troodonts are quickly captured. If there ever was clear demonstration that troodonts are not inherently superior to other maniraptors in-universe, this is it.
Sampson and Jeff misleading Djhey with a made-up genus name to prevent him from immediately using his device on them.
Kollin tricks a guard into spilling some acid, which kills the guard and frees the captured heroes.
Kim-Lee and Kollin mowing down an army of mutated creatures.
Djhey tormenting Feduciucc by getting him to meet BANDits and MANIACs, which has the effect of finally getting him to question his beliefs.

In "Ton-Zilla", the heroes quickly coming up with a plan to defeat Partay_Animal, and constantly shooting him down whenever he tries to turn the situation around.
