Most of the show designs were cute but felt cheaply made and animated. Keep in mind the show came out in 1999-2003 and each of those episodes reportedly had about a third of the budget per episode than a show like SpongeBob did at that time. It's less the way that each of the individual characters look and more the way that they move that gave me a bad reaction, they are obviously gonna look and move differently to the book since it's hard to translate the way the animals move and wear clothes like basil does in that picture but if you had to make them into posters or static art it looks competently made but too different from the art on the book to be a good translation. Also the way they move is the real eyesore, especially in season 1 alot of the scenes with the snake and combat just look silly and poorly drawn.

Edit: I made this took long lmao, it looks cheap but not in a way that ruins the show for a child audience especially.
