Those are correct; list updated. Had Super Celsius made it to the character specific clues I would have described him as an attempt to teach Americans something that most of them didn't accept (or something along those lines), as Americans ultimately decided to stick with the imperial system. Sources conflict as to whether Sabrina first aired in 1969, 1970, or 1971, which is why I placed Salem in the 60s.

Ikura has the 15 remaining bonus shots.

 

60 Mr Gruff, Teamo Supremo

180 Made Man, Awesomes

Yeah, I had to figure out the shows and then scan through episodes to identify the last few.

246 Ms Violet, Tiger and Bunny

Sometimes it was either scan a video or leave them out entirely. There were some (and I wish I had maintained a list of these for future updates) that I couldn't even find a video to do a screen capture. In one case I could only find fan art. I agonized over that but ultimately left them out in order to be as accurate as possible.

246 is correct. List updated.

207: I can't identify the exact species because it makes up most of the character's name but appears to an undead version of a mammal of the family canidae. I say likely undead because the character is an enchanted clothing item version of that family.
 

I'm struggling with 207; I can find shows that those creators both worked on, but not in the same episode afaik, and in the shows I see canidae characters but none who resemble 207. Hmm. 

How are the two names you mentioned credited in the episode/series in question?

207. Foxy, OK K.O.!
