[Windows][1998-2001] Game where you play as a wolf looking for bunnies across the levels.

This was a game I played a lot as a child at some point between the late 90s and the early 2000s. It was a 3D, blocky grid-based platformer where you played as a wolf(?) in yellow shorts looking to find a bunch of bunnies(?) scattered around the level. (I think they were bunnies at least, that's what the desktop icon was.)

I remember there were red, blue, and green doors that you needed to unlock to progress. Or they were portals, Or that was just the level exit. I can't recall, but they were hollow doorframes.

I remember the first level was grassy, it was like a boxed-in canyon. There were trampolines. One particular memory, I found that the wolf guy could hop side-to-side, and mashing the button sent him out of the map (meaning it needed to be reset).

Another level was a beach, that's where I remember the doors the most. The doors may have led up to cloud pathways?

Another level was a castle, it had a giant spider patrolling back and forth across a path. Unfortunately I didn't play this level much because the spider scared me.

Control-wise, all I can recall is that you hopped from grid space to grid space (a little like Frogger and a bunch of other games from that period) with the arrow keys, and you could also side-jump left and right. (For some reason my dad's keyboard had two more left and right arrows that were green and mapped to this specific control.)

I don't really remember what the game sounded like, unfortunately.

It may have been called "Tiny Tales" "Tiny Tails" or "Catch Tiny" but the details elude me.
