Straying away from his usual scrawny-sized roles, Tom Kenny provided the voice for Eduardo, one of the main characters in Foster's Home For Imaginary Friends. Despite his menacing appearance, Eduardo is a sweetheart and more often than not a nervous wreck. Tom Kenny's heavy, gruff tone is the perfect contrast.

The major downside of this performance is Kenny's poor Spanish. This might have been overlooked back in the early 2000s, but it is much more frustrating today. Still, Kenny's performance adds an endearing nature to Eduardo, making him such a lovable character.

Sharp-eared viewers might recognize Tom Kenny's voice in Camp Lazlo, as he voices the character Scoutmaster Lumpus. There's an emphasis on that "might," however, as he takes a much heavier tone of voice than normal.

This is why Tom Kenny's performance as Dog is so important. He manages to bring out Dog's goofy nature and convey his personality perfectly despite the relatively simple visual design.
