FERAL Animal Survival Growth Boosts: INSTA-GROW vs INSTA-ELDER

Quick answer

FERAL Animal Survival sells two instant-growth developer products: INSTA-GROW (100%) for R$ 39 and INSTA-ELDER (200%) for R$ 99. INSTA-GROW is the cheaper of the two instant-growth listings; INSTA-ELDER costs more than double and is named for elder, the final life stage.

• INSTA-GROW (100%) — R$ 39
• INSTA-ELDER (200%) — R$ 99
• Growth can also be earned for free by hunting, drinking and completing quests
• Prices are the Robux amounts listed in the game's store; check in-game for the current figure

Both sit inside the game's Roblox developer-product list, which holds 12 items in total priced from R$ 9 to R$ 799. The two INSTA products are the only instant-growth items in that list; everything else is REVIVE products or Amber bundles. The prices here are the Robux amounts shown in the store listings when they were recorded, so let the in-game shop be the final word before you buy.

Comparison

Comparison

Product	Listed price	Store label	Makes sense when
INSTA-GROW	R$ 39	100%	You want the cheaper of the two listings
INSTA-ELDER	R$ 99	200%	You want the product named for the elder stage and accept paying R$ 60 more

The percentage in each name is printed exactly as the store lists it — INSTA-GROW is tagged (100%) and INSTA-ELDER (200%) — and the listings don't spell out how those percentages translate into exact stage jumps. So the honest way to choose is by budget and by the goal each name points to. INSTA-ELDER's name lines up with elder, the last of the game's four life stages, and it costs R$ 60 more. INSTA-GROW is the entry-level option at R$ 39.

How to choose between them

Decision guide

Choose for your situation

You want to skip some growing but spend as little as possible

Buy INSTA-GROW for R$ 39 — it is the lower-priced instant-growth product.

You want your animal at the end of the growth ladder and accept the higher price

Buy INSTA-ELDER for R$ 99 — it is the product named for the elder stage, the final life stage.

Your growth bar already reads close to the next stage or ability threshold

Hold off for now — hunting, drinking and quests earn growth for free, and abilities unlock as you pass their thresholds.

These pairings follow the product names, not observed effects — the store doesn't publish what each purchase changes.

One practical check before spending: look at your growth percentage in the game. It is displayed directly — a wolf in one playthrough read 43% toward adult — and abilities are gated behind growth thresholds, with each ability setting its own. The hippo's crusher-bite ability, for example, required 34% growth to unlock. If you are already near a threshold or a stage transition, normal play may finish the job without a purchase.

Why growth is worth Robux here

Animals move through four life stages: baby, teenager, adult and elder. A growth percentage tracks progress between them, and abilities stay locked until you cross their growth thresholds — the starter wolf's first ability did not open until it grew up, and the hippo's crusher bite needed 34% growth. That gating is the ladder these two Robux products are named for; the store listings show only each product's name and price, and don't spell out what a purchase changes in-game. For how the stages themselves work, see the growth stages guide, and elder players can read more in the elder stage guide.

The free route: earning growth by playing

Growth does not have to cost anything. In a wolf playthrough, growth came from hunting — each successful hunt paid growth — plus drinking and completing quests; that wolf grew from baby into a teenager and kept pushing toward adult. Its quest list ran to things like hunting a deer and resting for 75 seconds. If you are patient, that loop keeps the climb going — the recording follows it to 43% toward adult and stops there, with elder waiting as the final stage on the game's list rather than an endpoint shown on tape. The INSTA products read as shortcuts because of their names; nothing recorded shows a purchase or its in-game effect, so they remain optional rather than requirements. The how to grow adult guide covers that route in detail, the hunting guide helps with the food side, and new players can start with the beginner guide.

A growth boost you might catch for free

Boosts can also appear during normal play. In one wolf session at 43% growth toward adult, a "growth boost, growing 50% faster" popped up right after the player mentioned adding the game to favorites — but the recording never shows what actually triggered it, so do not treat favoriting as a confirmed way to get one. Treat any mid-session boost as a bonus on top of the free route, and let the two store products be the planned purchases.

What else shares the store

The other ten developer products do a different job. Five are REVIVE products — REVIVE BABY (R$ 9), REVIVE 2 (R$ 19), REVIVE GROWN (R$ 29), REVIVE ELDER (R$ 39) and REVIVE ELDER II (R$ 49) — a separate line covered by the revive guide. The rest are Amber bundles ranging from R$ 40 to R$ 799, the paid route to the game's Amber currency (see how to get amber). Watch out for the near-identical price tags: REVIVE ELDER also lists at R$ 39, the same as INSTA-GROW, but it is a different product with a different purpose, so double-check the name before buying.
