Well, (to be very honest, I could've sworn that I already answered a similar question... but then I realized that it was only publicado a día ago. So, I looked through my past respuestas that I've given...and it was publicado for the question, "Have tu guys noticed?” [posted por (Sasori166) a año ago]
link ...So, to not make tu guys go back and forth between answers. Here are snippits of what I posted/predicted before with UPDATED edits in brackets [].

"... so, the mentioning of Blowhole when Kowalski's invention almost destroyed the city in "Invention Intervention", Doris in Skipper's dreams, ..., and he seems to be más of a rival to Skipper [MORE] now than during the 1st [or in the beginning of the 2nd season] (I think it started after the Jiggles episode because I think Kowalski thinks his teammates [DON'T APPRECIATE HIM AS MUCH OR] his amor for science & his need to experiment). Also, he seems más likely to lie than the others if it benefits him (like in "Friend-in-a-box" & "Invention Intervention" when he dicho to Private, "something plausible, but not the truth" which is just fancy talk for lying) and not to mention, he doesn't seem to always follow orders if he feels that the order was unnecessary... (like in the "Golden Squirrel" special).
Point is, I think this is all just a build-up for the new [PENGUIN-DORIS-BLOWHOLE] special..., which will mostly likely be a another [AWESOME 1 hour] episode, like “Operation: Blowhole” [OR "THE RETURN OF BLOWHOLE"]. [I THINK IT WILL BE A KOWALSKI-CENTRIC EPISODE ALSO BECAUSE] ...they have been building-up his character más with each episode in season 2 with him being a mad-genius o him disobeying orders). The other characters only disobeyed a few times so far in Season 2, but Kowalski seems to be up to something in every episode [so far]. ..."

So, to add-on… I think Kowalski will find out what Skipper's dream was about, and whatever the secret was when Skipper told Doris ‘that Kowalski must never know’. I think the secret is EITHER about Doris being related to Blowhole, o about Doris REALLY BEING IN amor w/ Kowalski but promised Skipper that she will turn Kowalski down even if he asks for a date. Mostly cause Skipper already stated that his men needs to stay sharp & stay away from amor nonsense…Then, when Kowalski finds out about the news (WHATEVER IT IS) it will shocked him, and he gets mad at Skipper and Doris...probably cause he was humiliated más than 18x's when he asked Doris for a fecha and for Skipper keeping a secret as huge as (WHATEVER IT WAS) from him & just the fact that Kowalski IS quick to temper cause he gets mad…oh boy, watch out.
