A few days later.
Ybur had spent several hours and, with the help of his suction-cup tentacles, finally managed to climb the steep cliff and crawl back into the sewer.
"Exhausted... Dead tired..."
Ybur lay deflated on the ground like a punctured ball, gasping for air, "Climbing a slope is so exhausting; it almost killed me. I shouldn't have been so greedy before climbing up, eating so many Corroding Beasts... I've gained weight!"
Ybur's size had once again expanded, now a size larger than a husky. However, Ybur also realized that stamina, strength, and size didn't grow in perfect proportion. The larger the body, the more difficult it was to climb. Ybur hadn't yet grown to the physical limits of an adult black pudding Slime—adult size was comparable to a small elephant, but their speed was even a bit slower than Ybur's current speed...
Damn it! Moving speed; that's our black pudding's pain!
