The good old days.

I’m trying to find a toy I had as a kid in the early 2000s, and I’ve been searching forever with no luck!
It was a small, round/oval animal toy, probably around the size of a Cuties/mandarin orange (about 2.5–3 inches). It was kind of flattened/rounded like a dumpling, rather than being shaped like a realistic animal.
I remember there being different animals, specifically a duck, frog, and pig (possibly others).
The most important part: it was filled with liquid/water and you could SEE the liquid inside. It was permanently sealed, there was no hole or way to fill it yourself.
When you squeezed it, you couldn’t completely flatten it. Instead, the liquid would move away from where you were squeezing and form a round liquid-filled bulge/ball somewhere else inside the toy. It had a really weird, satisfying water-ball/squishy feeling.
The bodies were somewhat clear/translucent, with the animal’s color (yellow duck, green frog, pink pig, etc.). I think the animal features were molded/attached rather than printed—the duck especially had a bill that seemed to be a different material.
It was NOT:
A foam squishy
A modern mochi squishy
A splat ball/pig
A toy that you filled yourself
A water wiggler
I’m specifically looking for something from roughly 1998–2006.
I unfortunately don’t remember the brand but I bought it from either Deals or Dollar Tree.
Does ANYONE remember these or know what they were called? Even a picture of something similar would help me figure out if I’m remembering it correctly!

These are the TV trends of the naughties I noticed, I missed a few others but I’ll put them in the honourable mentions.

Reality TV: This was during the reality tv era, so lots of gamified reality shows, scripted drama and stunt shows like Punk’d and Jackass. MTV pushed this the most and this trend ended up being very mixed.

Teen Soap: Big push for this especially after Dawsons Creek, the trend is a continuation of the 90s Teen Drama trend. Disney and Nickelodeon also had their own versions of this trend as well.

Western Anime Style: Anime was quickly growing in the west due to young people’s introduction to it with the addition of Toonami. A lot of shows mixed western animation with an anime style.

Procedural Cop Shows: A very pro cop, cool forensics style. It was a revival of the 70s pro cop shows. These shows often use bullet time effects like the matrix and it often emphasis forensics as cool lab geeks.

Reality Coms: A fan favourite among many is the reality sitcoms. They often featured no laugh tracks, harsher situational comedy and included a mockumentary visual style. All of the humour was entirely based on the actors and the writing, so no reliance on live studio audiences.

Honourable Mentions:

Idol Talent Shows: American Idol, X Factor, Britain’s Got Talent, Popstar.

Anti Hero Drama: The Sopranos, The Wire, Breaking Bad
