|Banjo-Kazooie: Grunty's Revenge
- “Klungo's Gruntweeds seem to be a cross between Gruntlings and Whiplashes. When you get close, they'll try to squash you. They seem a little dizzy to me.”
- —Jinjo Oracle, Banjo Kazooie: Grunty's Revenge
Gruntweeds are a recurring enemy in the Banjo-Kazooie series.
Gruntweeds are plant-like enemies created by Klungo after mixing Gruntlings and Whiplashes together. In Banjo-Kazooie: Grunty's Revenge, Gruntweeds can be found in Spiral Mountain, Cliff Farm and Spiller's Harbor. They disguise themselves as grass and fly into the air to attack Banjo and Kazooie when they get close and can be defeated by using the Pack Whack when they land in the ground again. In Cliff Farm, a specific Gruntweed can be found blocking a pen with Bleaters inside and not allowing them to leave, causing Banjo to have to defeat it in order to help them.
In Banjo-Pilot, a Gruntweed makes an appearance at the cerimony that happens when completing a Grand Prix alongside other characters, mostly from Grunty's Revenge.
- "Hee hee hee, I having fun. I not let Bleaters come out of pen. Hur hur!"
- "You not stop I playing with little Bleaters. Hee hee, hur hur!"
