Unlike Brightney's 1 stealth, Shrimpo's 1 star stealth isn't 0. That's because his passive ability lowers his stealth to -99.
The only Toon who switches stats as part of gameplay is Razzle & Dazzle.
Looey was also originally supposed to change stats (1 for every missing heart) as part of gameplay, but his passive was actually an added multiplier, not adding a star into movement speed. Therefore, he doesn't count.
Not counting Shrimpo, the slowest extracting toons are Bassie & Blot , with only 1 in Skill Check & 2 stars in Extraction Speed.
The fastest extracting toon is Vee, with 4 in Skill Check & 5 stars in Extraction Speed.
Originally, Pebble was the slowest extractor, with 2 star Skill Check and 1 star Extraction.
Most of these Toons also have 3 in every stat, with the exception of Shrimpo (1 star) and Dandy (5 stars).
Razzle & Dazzle's stats don't count despite their cards technically saying so, as their stats change depending on the Floor.
Bobette was the only toon to have 5 on 2 stats. This was later changed in the 2nd part of the 0.6.1 update and Bobette lost one star from Skill Check.
Bassie is the only toon (excluding Shrimpo and Dandy) who doesn't have 3 on any stat.
As mentioned above, Bobette also once had the same occurrence.
Flutter & Coal have the exact same stats. This is so far the only case of this happening (excluding all of the characters with an equal stat spread, as shown above).
Technically speaking, Boxten and Looey are the only toons who can reach roughly 17's worth of stats consistently without the use of items and cards. Boxten is behind by 2% extraction speed (for every player in lobby, he gets 6%+, so it maxes at 48%), and Looey is off in walk speed by 6.67~% and run speed by 20% (He gains 20% movement speed for every missing , up to 1 heart; 15 * 1.40 = 21, 25 * 1.40 = 35).
Some stats are paired up with other stats/attributes, whether accidentally or on purpose.
