When Mr. Blik and Gordon were trapped in rising lava, Waffle manages to save them with his new lobster friends. How? By having them form a ladder.
Mr. Blik: There's something you don't see everyday.
Gordon, thankful of the lobsters' help, renounces from ever eating them again... but not before the awkward moment of where he describes how delicious they are cooked, and they all took a few steps away from the cats.
Mr. Blik and Waffle begrudgingly agree to disguise themselves as a unicorn to impress the Human Kimberly. Waffle 'calls frontsies" but Mr. Blik wouldn't have any of that.
And then when they're wandering around in the costume.
Mr. Blik: What are you doing?
Waffle: Leaving a trail so we can find our way back. I'm laying eggs!
Especially when it shows up at the cats' house, seemingly for revenge... until it breaks down and cries.
Waffle's laser show involves REAL lasers. They were helpful in stopping a zombie outbreak (also Waffle's fault) but the first time used they pretty much scared and harmed a good number of people, prompting Mr. Blik and Gordon to warn him not to use them ever again.
Gordon: Laddie, I said blue cookbook, green room. Green cookbook, blue room is... The Scottish Book of the Dead!
Waffle: Oh. That explains the long and mysterious incantation with sour cream.
Concerning the issue of their robot selves.
Mr. Blik: How do we usually get out of situations before?
The entirety of "Core-Upton", where the entire world turns into a Tastes Like Diabetes wonderland. Especially funny are Gordon, Waffle and Mr. Blik's transformations into a Pikachuexpy, potted plant and pull-string doll respectively.
Mr. Blik: Waffle, touch that string and you're mulch.
In the episode where the cats went to the moon, there was a part where Mr. Blik and Waffle were walking together, when Mr. Blik saw something:
In the same episode, the whole sequence where Waffle plays zero-gravity basketball. Eventually, Mr. Blik stands on the hoop and tells Waffle to give him the ball, and there's a brief scuffle that ends with Mr. Blik and the basketball falling through the hoop and Waffle happily sitting on top.
